Principles and features of microlight night vision
Principle: the instrument uses the night target reflects the low brightness of the night sky light stars and moonlight atmospheric glow and other natural light, will be enhanced and amplified to hundreds of thousands of times, so as to achieve suitable for the naked eye at night for reconnaissance, observation, aiming, vehicle driving and other battlefield operations.
Characteristics: Because the microlight night vision device is the use of night sky light to work, is a passive way of working, so it can better hide themselves, engaged in special work departments, such as the military, criminal investigation, drug trafficking, private investigation, night surveillance, security applications, it is the most appropriate.
Microlight night vision instrument has developed three generations, the first generation of three-stage cascade microlight night vision instrument (composed of three 0 photocells in series). The second generation for the microchannel plate type microluminescent night vision device, the third generation for the |||-V negative electron affinity potential photocathode like the enhancement of microluminescent night vision device. In the first generation to the third generation over the development of a super second-generation photocathode called second-generation plus, its technical performance is second only to the third generation of products. Microlight night vision devices such as fine classification then is 0 generation, 1 generation, 2 generation, 2 generation plus, 3 generation, a total of five grades. Microlight night vision instrument development to today, the technology has been relatively mature and good imaging quality, low cost, so in the future for quite a period of time, they are still the world's night vision equipment a major equipment. Second-generation plus and third-generation products with small size, light weight, clear image, full-featured, practical and other characteristics. Is the military, public security, armed police, customs, oil industry, news interviews, tourism, aquaculture, nature lovers, and other industries night work indispensable equipment. However, due to its core components of the micro-optical image enhancer is a high-tech products, the process is particularly complex, high cost, relatively high prices. But from the performance-price ratio, or quite good.
