This is also one of the reasons why people cannot observe normally in a dark environment. In the dark environment at night, in addition to the existence of low light, there is a lot of infrared light. All objects in the world emit infrared light all the time, so whether it is day or night, space is filled with infrared light. But infrared rays, no matter how strong or weak, cannot be seen by humans. The night vision device uses both weak light and infrared conditions to convert the invisible light (weak light or infrared light) signal from the target into an electrical signal, and then amplify the electrical signal to convert the electrical signal into the human eye. visible light signal. Photoelectric conversion is a common way for all night vision devices to achieve night vision.  like：Night Vision Goggles Buying Reference Guide Is it uncomfortable to use night vision goggles? Matters needing attention when using night vision goggles ,night vision scope， ...ادامه مطلب
