2. Principles of infrared night vision Telescope

This is the real military night vision mirror, There are two types of infrared night vision mirrors, one is active, the other is passive, and the active type is the night vision emitting a bunch of infrared rays. Essencequilt The dynamic type is to transform the infrared rays from the object itself into visible light. If there is no infrared source (most things that can generate calories can become infrared, such as creature, vehicles, flames, etc.), passive infrared night vision mirrors can not be seen. And active infrared night vision mirrors can be seen under any circumstances.

The situation of the infrared auxiliary Lights is different. The distance of the situation of the infrared auxiliary light is different.In fact, this is very simple, but it is still difficult to explore than novices just exposed to this night vision instrument.Below I will talk about, under what circumstances can the night vision be seen?Under what circumstances is it close?

1 The night vision instrument observes a distance in the case of all black and light light

1) The distance from the micro -light observation is generally based on 1/4 The moon is based on the conditions of the weather. 50-400 Mi, if the weather is darker, or if the environment is harsh, its micro -light observation distance will be closer.At present, even the night vision instrument of more than tens of thousands of yuan can not be observed in the micro -light to reach 400 Above me.The second -generation night vision instrument can only be achieved 200 Du Mi, usually 1000-3000 The night vision around the yuan, its micr -light observation distance is 50 About meters.

2) In addition to the quality of the night vision instrument, the full black observation distance was seriously affected by the infrared lamp distance.At present, the infrared lamps equipped with the night vision instrument are average 50 About meters.Second generation The night vision can be observed under the observation of all black 100 About meters.In our actual use, there are very few all black conditions.For the second -generation night vision instrument, it is basically not all black when used outdoors.For a generation of night vision instruments, I said earlier, even darker, even if it was all dark.
