Holographic printing technology to make anti-counterfeit labels attached to the surface of the packaging is the most popular means of security. Holographic images due to a combination of the latest achievements of the laser, precision machinery and other physical and chemical disciplines, with high technical content. The majority of small quantities of counterfeit grasp of the full set of manufacturing technology and the purchase of manufacturing equipment is difficult to do, so the effect of such technologies is significant. Wide range of applications of holographic anti-counterfeiting technology and other security technologies, people have different opinions, holographic security hesitates. There are hundreds of manufacturers able to produce such identification, and makes some really identify difficult to identify due to the many problems that exist in the technical, management, simulation identity but also as real. And at the same time, the green high power laser pointers can get a very high power now.
Greatly reduces the laser holographic anti-counterfeit labels to the original position in people's minds. Manufacturers too much, the surplus of products, excessive competition may be the primary cause of laser holographic anti-counterfeiting into a crisis of confidence. But from a purely technical perspective, the image sources, a single old-fashioned and recording material of the photographic technology, is also induced by the root of the crisis of confidence. Therefore, to strengthen management, improve the technology, production of high-quality three-dimensional hologram at the same time in the show, photography and recording material is constantly tapping the potential of improvement and innovation, grasp the holographic and other security technology is the combination of holography and printing combination, a combination of holographic and packaging development direction of the laser holographic anti-counterfeiting as the main direction of technological development, this is crucial. So the green Laser Pointers can meet the higher needs and requirements of the customer.
Below to introduce you to the history of the development of laser anti-counterfeiting technology: the first generation of laser anti-counterfeiting technology is molded laser hologram anti-counterfeit labels. The hologram is shooting crystal atomic structure using X-ray photos by U.S. scientists Berg (MJ ? for Buerger), and Gabor (D Gaber) theory of holography: two-beam interference principle, so that things light and another to produce the interference pattern to the phase "merge" up with a coherent object light beam (reference beam), the photosensitive film to record the phase and amplitude holographic images can be obtained. However, the hologram is taken in accordance with the principle of interferometry, the high density (resolution) photographic film records. And the green laser beam light is emitted by the green high power laser pointers.
Ordinary light poor monochromaticity, coherence, and thus the slow development of holographic technology, it is difficult to shoot a decent hologram. Until the early 1960s after the emergence of the laser, high brightness, high color and high degree of coherence features, rapidly advancing the development of holographic technology, many types of holograms are produced, holographic theory has been well verified, but because special requirements, the time of filming and reproduction from the date of birth, almost always been confined to the laboratory. The late 1970s, it was discovered that holographic images including three-dimensional information of the surface structure (ie, criss-crossing the interference fringes), this structure can be transferred to the photosensitive film of high density materials up. The laser beam of high power laser pointers is much brighter.
In 1980, U.S. scientists have used the embossed holographic technology, holographic surface structure is transferred to a polyester film, thus successfully printed embossed hologram picture of the world's first one, this laser holograms, also known as rainbow holograms, it is laser plate-making, video production on a plastic film, the bright lights of the diffraction effect, and the picture has a two-dimensional, three-dimensional sense of space, in ordinary light, hidden images, information to be restored. When the irradiation light from a particular point of view, would give rise to a new image. Embossed hologram image can be like printing large quantities of fast replication, lower cost, and can be used in conjunction with all kinds of printed matter. At this point, holography has taken a decisive step to the social applications. More and more customers would like to choose the green high power laser pointers as the useful and practical tool and assistant.
