Explanation:
Detailed explanation-1: -Traditional night vision devices use optoelectronic image enhancement, which works by sensing small amounts of infrared light that are reflected off objects and then electrically amplifying that light into a characteristic glowing green image.
Detailed explanation-2: -Infrared light is electromagnetic radiation in wavelengths that are wider than those of visible light. Analog IR night vision cameras can see in total darkness by beaming LED light in the infrared range on their field of view and then translating the resulting images to wavelengths that human eyes can see.
