There are various types of night vision telescopes, but most of them are powered by self-collimation, video tube or micro-awn tube, switching power supply and power supply and distribution system. Naturally, the illuminating night vision telescope should also be equipped with illumination lamps, in which the variable image tube or the micro-awning tube is the "cardiovascular" of the night vision telescope.
The phototransformer tube can transform the image of the illuminated image that is not visible here into the visible image, and the micro-light tube can increase the very weak light by tens of thousands of times or even more than 100,000 times, so that the human eye can perceive it. Night vision binoculars are afraid of strong light, because the variable image tube and the micro-light tube are afraid of strong light. Taking the image changing tube as an example, when the light irradiates the optical negative of the image changing tube,Optical negative transmission electronic device, the electronic device accelerates to the display screen under the high voltage field (16 ~ 21KV) and the effect of the electronic device lens, so that the display screen shows the overall target image that can be seen. If the light signal light received by the variable image tube is not bright, there will be more sending electronic devices, and the light signal transmitted from the display screen will be strong if it is not bright, and the image seen will be bright.
They are basically positively correlated. However, if the external light source is too strong, the number of electronic devices for optical negative transmission will not be improved to a strict level, that is, a saturation state occurs, and the overall target will not be clearly seen. If too strong light suddenly comes in, it is very likely that the optics of the pipe will be disabled, and the electronic devices cannot be sent, and naturally nothing can be seen.
Although the night vision telescope adopts strict anti-strong light countermeasures, its efficacy is to a certain extent, so the application is strictly and strictly followed by the actual operation. When encountering strong light or target calibration in daylight, put on the eyepiece cover or turn off the main power switch. Proper application of night vision binoculars can increase its service life and prevent unnecessary damage, so as to make full use of night vision binoculars.
