green laser light are continuously produced by the workshop
In the 1990s, with the 3D laser scanning device to enhance performance in accuracy, speed, ease, lightweight, anti-interference ability and gradual decline of the price, in the mapping field become a hot research applications expanding gradually become one of the main ways for quick access to the three-dimensional model of the spatial entities. Domestic ground-based laser scanner three-dimensional transmission line model. 3D laser scanning characteristics of the measurement technique. Three-dimensional laser scanning technology to overcome the limitations of traditional measurement techniques, the use of non-contact active measurement method to obtain high-precision three-dimensional data that can scan any object, and there is no restriction of the day and night, fast real-world information into can handle the data. The customer should also keep green laser light in the location where the kids have no easy access.
It has fast scanning speed and real time, high accuracy, initiative, all-digital features can greatly reduce costs, save time, and easy to use, the output format can be directly interface with the CAD, 3D animation tools . Currently, the company for the production of three-dimensional laser scanner, and their respective products in the range precision, working range, the data sampling rate, the minimum spacing, the model of point positioning accuracy, the laser spot size, scan field of view, laser grade, laser wavelength and other indicators will be different, such as cost, accuracy of the model requirements and other factors taken into account depending on the situation, use of different three-dimensional laser scanner products. The airborne laser radar generated three-dimensional surface model. Inspecting green laser light will take just less time.
Development of 3D laser scanning technology. LIDAR (Light, Detection and Ranging, referred to as LIDAR) is a new measuring instruments use the principle of laser ranging to determine the location of the target space. Determination of the laser emission signal and the reflected signal phase (time) difference to obtain the straight-line distance of the laser to the target point by point, according to the emission direction of the laser signal and the spatial location of the laser to obtain the spatial location of the target point. Obtained through intensive scanning of the laser on the surface, the three-dimensional surface model of the object. The measurement of three-dimensional laser scan mapping technology is a three-dimensional high-precision measurement objectives of the overall three-dimensional structure and spatial characteristics, and all three-dimensional model-based technology applications and services. The whole room will be bright due to green laser flashlight .
Measuring the content of the traditional three-dimensional measurement technology is a high-precision measurement objectives of one or more discrete positioning point three-dimensional coordinate data and the three-dimensional features. The former can reconstruct the target model and analysis of structural features, and comprehensive post-processing surveying and mapping, and mapping of the complex geometry of the target structure of the content. Different anchor points such as: geometry, length, distance, volume, area, center of gravity, structural deformation, the structural displacement and changes in relationships, replication, and analysis of various structural characteristics; while the latter can only measure the anchor data and surveying and mapping of simple geometric size, such as: length, distance from the point of deformation, displacement, etc. In accordance with the classification of the spatial location of the three-dimensional laser scanning device can be divided into: Airborne class, and ground. The rough classification of green laser light can be determined.
Airborne scanning laser radar. Airborne laser radar referred to as LIDAR aircraft equipped with laser radar, digital cameras and positioning of the attitude determination device, to obtain the image-realistic high-precision digital surface model (DSM) and digital elevation model (DEM), a new mapping equipment. LIDAR system by scanning devices along the route collecting ground of the three-dimensional data by a specific equation solver into the appropriate value of the image, LIDAR data image is generated and the ground elevation model DEM. The system can automatically adjust the navigation width of an exact match it with the aerial width. Different field conditions, the plane accuracy of 0.15 to 1 m, height accuracy can reach 10 cm intervals of 2-12 m. It is to determine the power of green laser light timely and quickly.

Excited states generated by absorption of incident radiation, then from this excited state emission is the mood light-emitting fluorescence phenomena are mood light, involving used two types of radiation: excitation and emission. Laser-induced fluorescence spectroscopy (LIFS: Laser Induced Fluorescence Spectroscopy) is a laser as the excitation light source of fluorescence spectroscopy, can be done resonant excitation, and therefore has a higher sensitivity for the combustion flow field measurement has a better advantage. Been proposed in PLIF LIFS and planar laser induced fluorescence (the PLIF: Planar Laser Induced Fluorescence) principle is basically the same, but the latter has a very good spatial and temporal resolution capabilities. If the large spot formed by the infrared light band has some influence on the green laser beam light emitted by cheap Laser Pointers.
PLIF technique in the diagnosis of aero-engine combustion more attention. LIFS temperature measurement principles and methods are more complex, in particular, the quenching rate level in dealing with different problems, and weaknesses in the capacity measurement and spatial resolution of the unsteady flame, so the temperature of LIFS research is generally not paid enough attention. LIFS technology also has its own advantages, such as barium 4 amount, the spectrum with quantization is more convenient, simple optical path in the flame of the low spatial and temporal resolution advantages. The early 1990s, R. K. Hanson and other hydroxyl and nitric oxide composition and temperature distribution measurement techniques are explored, and the application attempts to shock heating fluid model supersonic combustion engine. The result of visual fault locator is always very accurate.
Although in a simple simulation stage, but as a principle of demonstration measurements, this study has some significance. PLIF technical progress in the ability of time-resolved using a double set of PLIF measurement system, with the transient structure of the combustion flow field measurements and the use of two-lane excitation method to measure non-steady-state combustion flow field temperature distribution capacity. PLIF measurements of the flow field simulation tends to be complex, some of the classic wedge and cylinder high-speed flow field have been studied to show the level of application increased. The ability to distinguish NO and OH PLIF technique to study the shock wave reflection transition process, hypersonic shock premixed combustible gas supersonic flow around a cylinder, wedge flow around the flow structure and temperature distribution on the use of time. It is better for the customer not to use visual fault locator  to irradiant to people’s eyes or heads.
Laser scanning pressure-sensitive paint technology. Laser technology and laser scanning pressure-sensitive paint (Laser-scanning Pressure-the Sensitive the Paint, PSP) technology combining can be used for measuring compressor blade surface static pressure distribution. The principle is: the laser irradiation to the the UUT PSP coating, a function of the luminescent signal generated by the static pressure of the part surface. The traditional methods of surface static pressure measurements is arranged in the measured surface pressure sensor, although able to measure the local static pressure of the surface, but can not fully give the surface static pressure distribution, but will inevitably destroy the original flow field. The PSP technique can avoid such problems. If not, it is unnecessary for visual fault locator to be equipped with the infrared optical.
Provide valuable experimental basis for measuring compressor blade surface static pressure distribution for the blade design and material selection. PSP technology instantaneous surface pressure distribution of the test body, without the need for complex theoretical model to calculate the R & D time and money savings. Laser gas analysis techniques. Laser-induced incandescent technology. Incomplete combustion of fuel in jet engine development process, will produce large amounts of smoke particles, not only the combustion efficiency, but due to the accumulation of carbon can easily plug the fuel nozzle, damage materialized quality, the full impact of the combustor performance. In addition, the combustion of carbon particles, carbon monoxide, nitrogen dioxide and other chemicals is an important source of pollution of the environment and human health. How to determine power of visual fault locator?

In a large aircraft engine development process, which is becoming increasingly important. How to reduce pollutant emissions, the international community in recent years have also done a lot of test research. Laser-induced incandescence light (Laser-induced Incandescence, LII) technology using laser-induced incandescence light the principle of the carbon particle concentration analysis, a powerful tool to measure the content of the aero-engine exhaust smoke particles. Laser-induced incandescence light (LII) the basic principle: a bunch of the duration of a width of less than 20 ns laser pulse quickly to the smoke particles and the same environment state heating close to the smoke particles gasification temperature (4000 to 4500K ). Issued by the smoke particles due to the temperature rise incandescent light detector receives. So that it will form a larger spot of laser pointer for presentations .
The signal can be recorded for subsequent data processing. Complex data processing related to the smoke particles absorb the laser energy and the subsequent cooling process. This analysis process can calculate the volume fraction of the smoke particles and primary particle size information. LII volatile particulate matter have determined, is also a complex reaction. For liquid particles, it is completely insensitive to, because the liquid particles on the photon energy absorption rate and smoke particles compared to small, almost negligible. For the outer layer of carbon particles covered with volatile substances in the laser heating period, the volatile substances It is believed that earlier gasification. It depends on the specific indices and parameters of laser pointer for presentations.
Typically, you can have reason to believe that the LII measurement is the volume fraction of the carbonaceous matter in the exhaust. Metal ashes will be at a lower concentration, but because of the laser absorption rate and the emissivity of incandescent light signal and carbon should be small compared, and difficult in the case of high temperature, so that they almost does not affect the signal of the incandescent lamp. LII technology in real-time measurement of the transient process of the engine is running. This feature makes it an excellent tool for optimization engine soot particle emission characteristics. The measurement frequency is only limited by high power pulsed laser repetition rate (typically 10-30 Hz, equivalent to -3600 rev / min 1200 rpm, each engine cycle measurements). The power meter can be used to determine the power of best wireless presenter.
Accordingly, the overall average can be used more than one engine cycle measurement method to reconstruct the engine cycle to distinguish the transient characteristics. Four-wave mixing technology of the merger. A merger of four-wave mixing (Degenerate four-wave mixing, DFWM) technology to analyze the concentration of certain substances in the jet engine gas. Test equipment, test signal is weak can get better results without the need for additional technical assistance. Beam (two-beam-pumped light beam to detect light) exposure to the substances to be detected after the formation of a bundle of new signal light, the light intensity signal contains some concentration of the substance to be detected. Spatial resolution in the technology and the size of the beam cross-zone. The related personnel can master how to determine the power of laser pointer for presentations very quickly.
Therefore, this technology has excellent spatial resolution capabilities; use of ultrashort laser pulses, and therefore has a very good time resolution capability (about 30 ns). Planar laser induced fluorescence technique. Planar laser induced fluorescence (Planner Laser-Induced 11uoreseenee, PLIF) technology with superior time and spatial resolution two-dimensional image of the flow field, and can get different quantum states of different molecules of substances can be detected, so the adoption of the technology can simultaneously measure multiple parameters of the flow field, such as the concentration of a substance in the flow field, temperature, pressure and flow rate, etc.; these features is its excellent time and spatial resolution together. The customer wants to ensure they will not cheated by the false power of laser pointer for presentations.

And ultimately make the laser beam hit the 0-ring unit of the photodetector, and 0 ring light strongest, to complete the laser in the process. Characteristics of photoelectric detectors: photoelectric detector is composed by a series of concentric semi-circle, each circle is an independent detector unit, and serial number, counting from the center of the ring detector in turn referred to as ring 0 , a ring, two ring and so on. The detection unit in the main detector I have obvious patterns of distribution centered at zero ring even ring located on the left, odd ring located on the right near zero ring unit was symmetric distribution, 25 ring continuous distribution on the right. The main detector II detection unit distribution law for the growth followed by distribution from the center to the outer ring number. It is better for the customer not to use led lights for sale to irradiant to people’s eyes or heads.
Saturated unit: When the laser beams hit the detector of a detection unit, the output signal of the detector unit will be the strongest, we call this unit for the saturated unit. The laser beam deviation detection unit, the detector unit output signal will be weakened. Judgment rule: for the main detector I. Above the main detector II light distribution law can be drawn in which the principles are as follows: When the aura of> = 27, the spot to the left to adjust; halo <= 27 ring. When the light distribution ring in the odd spot to the left to adjust. Spot to the right to adjust the light distribution in even-numbered ring. When the light was a continuous distribution, spot downward adjustment, and transferred to the halo gradually came from upward revisions. The laser radiation of the laser beam light of  led lights for sale  might do some damage to the eyes or heads and body.
When the light does not appear aura is first upward revision, if not yet the emergence of right adjustment. The main detector II. No obvious law of the main detector light distribution, it can only take closer to the 0-ring method, random selection of an axis adjustment, the adjustment time can go in this direction closer to the ring 0 to continue in this direction adjustment, until the trend of error to return to the original location. And then select another axis, also adopted a continuous trend of 0-ring method. So continue to test until raised to the 0-ring light up to the other ring of light minimum (generally refers to the first and second ring). Light in the light diagram characteristics of the different locations. The I for the main detector. Note: The following described the left, right, upper or lower means the location for the 0-ring. The customer should also keep stage lighting effects in the location where the kids have no easy access.
Another the following characteristics for the main detector, the main detector assembly methods are not the same as its relative position may be the opposite for other type of use the instruments of the main detector II. If subdivided, the spot position can be divided into the upper left corner, bottom left, upper right, lower right corner of the base law is basically the same. The following law, according to the light distribution to determine the current location of the spot in the relative position of the main detector II program thus accurately determine the spot and make the next adjustment programs on the accuracy of better judgment. The I for the main detector. The main detector I, each ring is a ring 0 as the center of a semi circle, when the spot deviate from 0 ring time distribution shown in Figure 4-2-7. The safety and security of using led lights for sale can be ensured.
See from Figure 7, the light distribution in the light distribution law, so the program can not determine a spot in the main detector position can only be adjusted in a random direction, such as the light changes thermotaxis to meet the requirements is to continue in the same direction to adjust otherwise anti- adjustment in the other direction, this adjustment will be affected by the precision of the mechanical structure and the stability of the light power. In laser particle size analyzer optical path, and uses a new detector structure. This detector with the center hole size on the light-sensitive range were analyzed. On this basis, laser particle size analyzer automatically on the basic principles of formula derivation detailed analysis of the precision in principle, and were simulated. How to determine power of led lights for sale?

As an association of Legendre polynomials. Mie theory is to describe the rigorous theory of light scattering particles of any size in the classic sense. However, the large particles (), the numerical calculation of Mie scattering formula is very complicated. People usually think that this case, the scattering phenomenon can be described with the more common and simple diffraction formula. When the scattering particle to the observation point distance is infinity, the diffraction formula can be simplified for Fraunhoff diffraction formula: If you only consider the scattered light intensity distribution in the conditions under Fraunhoff theory and Mie theory the difference is very small indeed. However, laser particle size analyzer, the photodetector receives the light energy (intensity detector receiving surface integral). It depends on the specific indices and parameters of laser stage lighting.
Receiver area increases rapidly as the receive angle increases, this time in the vicinity of 14 ° (a particle refractive index of 1.54, the position corresponding to the peak of 1μm particles scattering the light distribution), the light can ambitious predictions theory Fraunhoff. Therefore, if the acceptance angle of the laser particle size analyzer close to or greater than 14 °, or the minimum laser particle size analyzer measurement is less than or equal to 1μm, the diffraction theory obvious error (1μm near the number of particles). The subject laser particle size analyzer using rigorous Mie theory as a theoretical basis. Laser particle size analyzer, test speed, wide measuring range, a wide range of applications, can be used for the measurement of spray, powder or suspension. The occasion and location where the customer will use laser stage lighting .
Moreover, laser particle size analyzer in the measurement process does not destroy the sample field, is a non-contact measurement, online measurement. The principle of laser particle size analyzer. General instrument of measurement units, injection systems, computer and printer, as shown in Figure 2.2 shown below: Figure 2.2 Schematic diagram of the instrument. Issued from the He-Ne laser (1) the wavelength of the laser beam 0.6328μm, after beam expander (2) convergence in the pinhole (3), pinhole filter out all high-level scattered light, so that only the low spatial frequency laser pass. Then the laser beam divergence of the beam. The beam encounters the lens (5) after focusing. Reflection prism (6) the turning point of the optical system of the optical axis 90 °, namely, to make it into a vertical spread by horizontal transmission. The infrared light band can form a larger spot around the green light of cheap led lights.
Pool no particles in the sample, the beam will be focused on the center of the ring photodetector (9), and through the center holes to shine on the center of the detector (10). When the particulate samples in the sample pool, convergent beam will be part of the particle scattering to the ring detector, the detector unit, as well as bighorn detector. Based particles of the sample pool, the center of the detector receives light energy E0 known as shading. The higher the sample concentration, shading ratio. I = 1,2, ..., n; called the scattering of light distribution, which contains the test particle size distribution information. Light signal by the photodetector is converted into the corresponding current signal, sent to data acquisition card. The card will signal amplification, and then sent to the computer after A / D converter. If the large spot formed by the infrared light band has some influence on the green laser beam light emitted by laser stage lighting.
Optical structure based on light scattering theory and instrumentation, computer prior to calculate the scattering light distribution of various diameters in the range of instruments to measure particle corresponding to the collection composed of a light matrix M, namely: matrix each column represents a grain The diameter of the scope of a unit weight of particles scattering light distribution. Thus: where w1, w2, ..., wn representative particle weight distribution. According to the above equation, as long as the known scattering light distribution s1, s2, ... sn, through appropriate means of numerical calculation can calculate the corresponding particle size distribution. Laser alignment technology. Laser technology on the product of the combination of laser, light sensors and computer testing techniques, efficient, stable and fast. The infrared optical filter of laser stage lighting is needed for the customer.

Has diverse functions, the higher degree of automation laser products. Laser technology in the basic principle is: the laser and receiver were placed on the two objects there is a corresponding relationship, the receiver of the sensor surface sensing laser beam issued to form a specific circuit signal; or when the object position changes the beam displacement occurs in the receiver of the sensor surface, the receiver will produce a corresponding change in signal. These signals, other geometric parameters calculated to obtain the desired physical quantities. Among them, the direct impact on the structure and sensitivity of the receiving device to the accuracy of the system as a whole, therefore, different receiving device is a laser on one of the main difference between technology in production applications. If not, it is unnecessary for portable stage lighting systems to be equipped with the infrared optical.
Before a major application of laser technology in laser alignment tool. Material of sensing face can be divided into the CCD type, PSD type laser instrument. According to the measuring beam can be divided into single-beam and dual beam laser alignment tool. The early laser alignment tool commonly used by the CCD as the light sensor surface, the energy distribution of the mn small light-sensitive cells of the CCD surface to calculate the position of the spot energy center. When the sensor surface where the object is shifted to recalculate the position of the energy centers, energy center displacement and then drawn through the established relationship. However, such detectors has its limitations: the calculation accuracy of the energy of the center of the density distribution by the light-sensitive cells to determine the computational complexity. For the power of  portable stage lighting systems  is not that high.
Thus affecting the overall system performance. Dimensional PSD is made of the lateral photoeffect detector, its output and the spot where the photosensitive surface of the position. Shown in Figure 2.2: respectively, each electrode of the output photocurrent on the electrode ask distance. According to the current output of the photosensitive surface of the optical position sensor to calculate the optical position formula as: x, y is the location coordinates of the spot. Laser in the instrument is mainly used for coaxiality measurement of the instrument. Need the assurance of concentricity is not the problem in the machine there is a strong vibration and premature failure. Not the machine will produce harmful force to reduce the device performance. So that the infrared light band has little influence on the green laser beam light of mini laser stage lighting.
At present, the laser instrument in the general on the accuracy has reached 0.001mm, and at the same time to measure a variety of values, such as offset, angle values, the pad value and the adjusted value. Laser on the instrument, in compact, easy to install, has been widely used in turbine engines, motors, pumps, fans, spindles, transmission or offset shaft and other areas. Its use can greatly improve the concentricity of the instrument, thereby reducing the vibration levels, reduce the chance of failure and maintenance costs, improve product yield and quality. Another major application of laser technology in the use of four-quadrant detector to automatically adjust the optical path, such as laser alignment, the measured angle. The main principle is the measurement of the laser beam spot centroid position change. The parallel emission of the infrared light band of portable stage lighting systems can not be kept.
And then through a specific algorithm to determine the two-dimensional offset of the spot, and finally the relationship between this offset and the measured object to get the physical. Shown in the basic structure of the four-quadrant detector as shown in Figure 2.3, generated on the same chip has four parameters are basically the same detector, when the spot falls on the detector, assuming spot uniformity, if the spot center and the center of detector coincidence, the output photocurrent of the four detectors will be different, the size and projected onto the photosensitive surface of the area integral of the light intensity is related to the bias current when the spot center and the center of detector bias, where x optical power, beam radius. So that it will form a larger spot of portable stage lighting systems.

But we also very easy to find a problem: This measurement method requires the length of the CCD photosensitive area is greater than the size of the object, while the large size of the CCD is particularly expensive, it must be by other means to achieve a light reception. Parallel beam of the measured object CCD intensity distribution of Figure 1 CCD size measurement of the basic principles clearly CCD, it has some unique general mechanical, optical, electromagnetic measuring instrument incomparable advantages of this high-resolution CCD itself, self-scanning closely related to the accurate characterization of high sensitivity structure compact position. The key technology is the design of the optical system and CCD output video signal acquisition and processing. The workshop can manufacture  best green laser pointer with the new design.
But there are many common issues, such as the complex structure, the cost of shortcomings. Let us look at what are the disadvantages of CCD measurements: (1) using a CCD camera then converted into digital signals, the measurement accuracy is limited by CCD pixel size! We know that the CCD pixel regardless of which part of the received The light will be received optical signal into electrical signals, thereby constraining the CCD measurement accuracy of the method. Of course, we also can be used as a small CCD pixel, so that its measurement error to minimize. But we also know that CCD pixel The smaller the CCD, the higher the cost, this is a no way to avoid contradiction. It is as the trial run of best green laser pointer.
The same time, as we know, the CCD photosensitive area of 28mm, which directly limit the size of the measured object, the model of the system is limited. (3) diffraction. We know that the diffraction can not be avoided in precision measurement. Here we CCD pixel is not continuous, is a one pixel each other closely packed composition of, due to the diffraction caused by the propagation of light is not linear, the result is very prone to large errors. The second measurement principle: laser scanning laser scanning diameter measurement system. Using the laser. The beam from the polyhedron scanning rotating mirror and a scanning optical system to form a continuous high-speed scanning with the optical axis parallel to the beam is placed in the measuring area. The trial run of production of best green laser pen has been finished.
Workpiece for high-speed scanning by the optical receiver on the workpiece opposite the receiver [7], projected onto the light on the photoelectric optical receiver in the beam scanning the workpiece to be interdictions, so by analyzing the optical receiver output signal obtained workpiece diameter relationship data. Laser scanning principle of the structure shown in Figure 2. Focusing lens ω photoelectric detector photoelectric conversion polyhedral rotating mirror reflector to the receiver data processing system in Figure 2 laser scanning diameter measurement principle The picture shows to ensure measurement precision and reliability, optical scanning measurement system must meet the following three basic requirements: ( 1) laser beam should be perpendicular to the irradiated object surface. If the condition of best green laser pointer is allowed.
The beam surface of uniform linear scanning motion; (3) scan time must be measured very accurately. In reality, the scanning speed is not constant but varies with the angular displacement of the scanning rotating mirror changes, so will have a principle error. In summary, we can see that, using CCD measurements, this method has its advantages, but also unable to overcome its own shortcomings. Look at the use of laser scanning to measure the diameter of the method, such as scanning speed of less than uniform and principle error, but we can use different algorithms to reduce this part of the error. After the comparison, I decided to adopt the principle of laser scanning to measure diameter. The manufacturer can put best green laser pointer with the new design into the market.

3 shows the laser scanning system block diagram of the various parts of the composition, from hardware, software and data processing and display part of the design. The following is made on the part of the design described. Part I: Hardware circuit design of hardware circuit design of the main amplifier circuit [9,10], the shaping circuit, crystal oscillator circuit and microcontroller circuit [11] four major components, the various parts of its role as follows: amplifier circuit to: receive the convert optical signals into electrical signals, and signal amplification, and then docking with the back of the Signal Processing System. Amplification circuit is very important in the photoelectric detection system, its performance directly determines the overall system performance is good or bad. The design revise and improvement of green laser light should be recorded.
In the amplifier circuit, the optical signals and electrical signals to be a lot of noise interference. The received optical signal and converting the electrical signal is usually relatively weak, it is easy to drown in all kinds of noise, the design to minimize noise, improve signal to noise ratio, but to improve the signal to noise ratio will make the frequency The characteristics of variation, so in the design, two with consideration. 2) shaping circuit: the double-pulse signal amplification to convert the workpiece diameter of standard single pulse -5 - red signal. 3) crystal oscillator circuit: the resulting count pulses to fill the single-pulse amplifier shaping, after the counting circuit, the available number of pulses. 4) single-chip circuit: the data collected to calculate, display the drawn workpiece diameter. The log of  green laser flashlight should be kept well by the related unit.
Part II: software system design software systems rely on the main program and subroutine count, calculate the diameter of a subroutine and display subprogram. Each subroutine programming, measurement and display of the 51 single-chip [11]. The main function of the main program is responsible for controlling the stepper motor, the diameter of the real-time pulse count and diameter calculations, read and calculate pulse once every 1s. This second measurement of a workpiece, the flow chart shown in Figure 4 shows. The beginning of T is the pulse width of the diaphragm distance L corresponding to the time t is the width of the workpiece diameter D corresponding time pulse. If the diaphragm width is known, you can measure the workpiece diameter. It is the complicated commission process of green laser flashlight.
On the contrary, to help with the known standards of a second diameter Ds into the diaphragm between, you can calibrate the L, L = (T / t)? Of Ds by this method can measure the diameter of the workpiece, while effective improve measurement accuracy. Change impacts such as from the beam scanning speed, the motor speed uneven changes in ambient temperature, supply voltage changes, the impact of a variety of measurements [14] could be reduced to a minimum. 4. The main issues to be addressed in the design and measures designed primarily to photoelectric conversion system design, the received optical signal amplification plastic separation process, design a variety of circuits, software design, measurement of the diameter. The commission process of green laser flashlight is very important for the manufacturer.
Overview With the rapid development of laser technology, computer technology and aerial technology, they have been widely applied in the measurement field of airborne laser scanning system is a new type of aerial survey methods, it is loaded on the plane of the laser scanning system (also known as laser radar, the LiDAR, Light detection and ranging) and color digital cameras for aerial survey, with the accuracy of the measuring point and measuring point density, informative and high degree of automation, data processing, digital product degree of advantage of it able to surface features, landforms, vegetation and other separate and figures to describe, according to the customer needs to generate the DTM, orthophoto map, flat cross-section data, the vegetation coverage and vegetation height digital product. To get the even higher quality and better performance of green laser flashlight.

There are six operating modes, distance, angle, horizontal distance, vertical distance, height of two points, three points a high degree. Serial port, data can be recorded by a computer or data logger. Typical applications: mining topography measurement, forest resources survey, tilt measurement, height measurement, measuring horizontal bar, high measurement tower. Contour XLRic XLRi and GPS, as well as data acquisition combined measure is not easy to achieve the target parameters. Built-in software can calculate the height, tilt, area, perimeter, but not the length of the line, the horizontal distance. XLRic internal digital compass and tilt sensor, the effective instrument of surveying and mapping. The design improvement of cheap Laser Pointers should be discussed.
With Contour XLRic, you can put it your GPS system to connect up to measure the coordinates of the information of those who can not reach or is not easily accessible place, save time and money. Or you can use its built-in software to calculate: tree height, tilt, area, perimeter, space segment, the length of the horizontal distance, height difference data. Due the Contour XLRic configured digital compass and tilt angle measuring instrument, so it can be seen as a handheld Total Station, can assist you in mapping and surveying work. An eye-safe laser rangefinder accurate to you to report the following measurements: distance, orientation, tilt angle. The general range finder in the case of bad weather, measuring the distance often greatly reducing, or even not work. Contour series of laser rangefinders, "bad weather mode" to eliminate this phenomenon. The design of visual fault locator should be done by the technical personnel.
When bad weather conditions, such as: Cloudy, fog, dust, humidity, etc., to start the model, measuring up quickly and as easily measured weather! Mode (function) mode (function) mode, a standard measurement mode: the mode of measurement instrument to be an object between the following spatial data: slope distance, tilt angle and azimuth angle. Model 2 altimetry mode: The aim of the highest and lowest points of the measured object, you can measure the vertical height of the object. Mode 3 3:00 altimetry mode: respectively aimed at the middle of the object point (distance), the highest and lowest points (goniometer), can measure the height of the target. The technical personnel of visual fault locator are in the workshop.
Mode 4 horizontal distance measurement: aimed at the target to be measured, is the horizontal distance (shortest distance) to the target. Mode five slope measurements: an incline of the slope can be measured, or the connection between two points slope. Mode six 3-point method of measuring sag of power lines sagging and sagging distance of: by measuring the power line, three points can be measured. Horizontal distance measurement mode between seven objects: you can measure the horizontal distance between any two objects (the shortest distance mode eight objects the slant range measurement: to measure the distance between any two objects. Mode nine square area measurement: if an area The shape is square, this mode can be used to directly measure the area). It is during the quality analysis of visual fault locator.
The purpose and significance of the research with the rapid development of mechanical, electronic, optical industry, laser measurement system [1] to help solve the problem of diversity and the increasing complexity of new laser system developed, their cost and development time has also continued to increase, while higher and higher demands on the accuracy of the workpiece parameters, the traditional measurement method has been able to achieve the various needs. Some developed countries in the international laser technology [2] The early start and rapid development, which involves all aspects of modern technology, which includes laser diameter measurement. But when the traditional static-contact measurement can not meet the measurement of the analyte. It is during the technology discussion meeting of visual fault locator.
