Night vision observation effect
Shimmering night vision technology, also known as image enhancement technology, is through the night vision goggles with image enhancement tube, the target image of the weak light irradiation enhancement for observation of the photoelectric imaging technology. Microlight night vision device is currently the largest foreign production and the most widely used night vision equipment.
Infrared night vision technology is divided into active and passive two. Active infrared night vision technology is through the active irradiation and the use of target reflection of infrared light source to implement the observation of night vision technology, corresponding to the equipment for active infrared night vision device. Active infrared night vision technology has a clear image, low cost. Passive infrared night vision technology is the target itself with the help of infrared radiation to realize the observation of infrared technology, simply put, according to the temperature difference to imaging, very low resolution, but has its special purpose.
Russia's night vision instrument belongs to the 3rd generation of microlight night vision device, improved photocathode semiconductor materials, making the microlight and infrared are very sensitive to the infrared night vision device and microlight night vision device united in an instrument in the night on a sunny day microlight night vision device function, in the rain, foggy days at night to emit infrared rays from the active infrared night vision device function, and the effect of the distance is farther than the second generation of the more.
At present, the development of thermal imaging technology is also very fast, but, due to the high cost, poor imaging quality, inaccurate target identification and other technical problems, so far the United States, Russia have not been equipped with a large number of it * *, the United States, Russia has not been equipped with a lot.
Through the test: monocular night vision device in general in the absence of light (no visible light, out of sight) in the case, without the transmitter is about 10 meters, open the transmitter can see about 50 meters, binocular night vision device with the distance from the different models can see about 50-100 meters. In the visible light (shimmering light such as: starlight. Moonlight. Street light. Pu cloud) can see hundreds of meters to several kilometers.
