Followed the pattern of compliance with the published pattern, but the average consumer only can be discerned only when careful comparison of two different versions of the holographic label. Did not prevent the anti-counterfeit labels re-use of technology. There is no technical method to prevent the re-use of packaging bearing counterfeit labels was. Did not prevent counterfeiters use of bribery, bribery and other means to obtain the technical method of the anti-counterfeit labels. With the development of science and technology, the progress of mankind. Laser speckle imaging in more and more areas to a wide range of applications, such as medical, environmental, camera, and so on. Progress of laser speckle imaging. Medical progress. In medicine, we can use the laser speckle imaging techniques to monitor spinal cord blood flow. The personnel can put forward advice and suggestion about laser pointers.
Spinal cord blood flow dynamics of the change has been a hot topic in the Spinal Cord Injury Study. At present, the commonly used animal spinal cord hemodynamics spatial resolution is not high enough or need to add exogenous markers, spinal cord injury, a variety of defects. Brier s proposed in the 1980s, laser speckle imaging technique gradually being used for monitoring skin blood flow distribution in the fundus. More recently, Dunn et al [1] the use of the technique successfully monitored cerebral ischemia and cortical expansion of the inhibition of rat cortical blood flow in the model dynamic changes. Laser speckle imaging as a new regional flow rate monitoring technology can be achieved without scanning conditions. It is the advice about how to improve the quality and performance of 5MW Laser.
In rat cerebral blood flow in ultra-deep hypothermia under laser speckle imaging monitoring. This is the Ministry of Education Key Laboratory of Biomedical Photonics, Huazhong University of Science and Technology - Wuhan National Laboratory for Optoelectronics (chips), Zhang Li, Peng-Cheng Li, Ni Songlin had Shaoqun, Luo Qingming, such as a few people together to complete. Acute onset of severe acute cerebral ischemic diseases, severe illness, a serious threat to human health, the treatment of severe acute cerebral ischemic disease at home and abroad is still less developed. Hypothermic brain protection to a significant protective effect on cerebral ischemic injury has been a lot of experimental research and clinical applications proved [1,2]. (9) low-temperature treatment to improve cerebral blood circulation, stabilize vascular function, reducing the energy metabolism of brain cells. The document can be the reference of laser pointers.

The study found that brain temperature decreased more low, the less nerve cell energy metabolism and oxygen consumption, the better the brain cells, the protective effect can be effectively blocked serious cerebral ischemic diseases the pathological damage of brain cells process [3]. Brain tissue temperature quickly dropped to the ultra-deep hypothermia (≤ 16 ° C) level, while body temperature remained at normal body temperature, not only to achieve good brain protective effect and to avoid systemic deep hypothermia treatment in the complex heart and lung damage caused by temperature process [3]. But the ultra-deep hypothermic brain protection mechanism is unclear, and need to clear deep hypothermia cerebral protection time window. The clinic is necessary to ensure the normal biological tissues from the damage of ultra-deep hypothermia. The log of laser pointers gathers much information.
