Visible at night is very weak, but the human eye can not see the infrared is very rich.

Infrared vision can help people at night to observe, search, aim and drive the vehicle. Although people discovered infrared light very early on, it was limited by infrared components and infrared remote sensing technology developed very slowly. It was not until 1940 that Germany developed lead sulfide and several infrared transmitting materials that made the creation of infrared remote sensing instruments possible.
