Studies have shown that 1.064μm band illustrates the value of the lower eye, a strong laser radiation will cause serious eye damage, and thus to the training and testing has led to great difficulties. The United States, Germany and other countries have this type of range finder to the limit. Ranging poor weather. Nd: YAG laser rangefinder laser wavelength generated in the atmospheric window near infrared wavelength region, so its ability to spread in the atmosphere is low, vulnerability to environmental interference. Dust clouds in there, Yin Ting and other weather conditions or battlefield smoke and dust environments, ranging not only can not guarantee the accuracy and quality, or simply not work. That is greatly influenced by the work environment, meet around the clock. The technician will show the disassembly operation of green laser pointer this afternoon.
Poor compatibility. WZ123 main battle tanks in China's new car, for example, the car has been equipped with a thermal imager. The operating wavelength in the 3 ~ 5μm (in infrared) wavelength domain of 8 ~ 14μm (far infrared), is two infrared atmospheric windows. Work due to thermal imager band is 8 ~ 12μm, 1.06μm and therefore the Nd: YAG laser rangefinder and its poor compatibility. Because they work in different bands, penetration is not the same, so not only can not achieve the common parts and components, and can be observed with a thermal imager to the target, can not necessarily be Nd: YAG laser rangefinder to measure it the distance. The third generation of human eye-safe laser range finder laser range finder, the West as ESLRF. 1.5Xμm CO2 laser rangefinder and laser range finder is more research on the eye-safe laser rangefinder. The group leader is reporting the safety situation of green laser pointer workshop to the director of led flash light workshop.
CO2 pulsed laser range finder is in the 1980s mainly for the 1.06μm Nd: YAG laser rangefinder shortcomings developed a new generation of eye-safe laser rangefinder. Its main advantages are: penetrating ability. CO2 laser rangefinder operating wavelength is 10.6μm, which is located just 8 ~ 14μm wavelength far-infrared atmospheric window, so the atmospheric transmission performance, through the large aerosol, Ting battlefield smoke and dust and strong, by the work environment effect is small; for eye safety. The human eye 10.6μm wavelength of CO2 laser transmittance is very low and difficult to damage the retina, which is not easy to make the exposure of the human eye damage or blindness, training and exercises in safer; with existing wavelength of 8 ~ 14μm thermal imager compatibility. The skilled engineer has found the technical problem of green laser pointer put forward by the customer.
In addition, CO2 lasers have high energy conversion efficiency, can be highly sensitive heterodyne detection technique, in the 9 ~ 11μm band capable of firing more than one line. Currently, the performance of many operations and technology advanced main battle tanks, has been equipped with a CO2 laser rangefinder. Such as the U.S. M1A1, M1A2, South Korea's 88-style, the British "Challenger 2" and so on. CO2 laser range finder good performance in the Gulf War has been sufficiently validated. CO2 laser rangefinder there are also a number of factors restricting the development, including: 10.6μm of the CO2 laser wavelength attenuation can easily be absorbed by water molecules, water vapor in the atmosphere under the conditions of density, limiting its maximum ranging capability , especially rain and snow covered the target, the target presents multiple mirror reflection symmetry, the CO2 laser ranging negative. The customer said that if the price of green laser pointer is low enough, their company will add more orders of green laser pointer .
