There are various types of night vision goggles, 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 convert the illuminated image that is not visible from this to 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 signal light received by the variable image tube is not bright, there will be more sending electronic devices, and the light signal light transmitted from the display screen will be strong if it is not bright, and the image seen will be bright.
