Night vision binoculars vary from the regular type bino. There are three types of technologies used – digital night vision technology, thermal technology, and starlight technology.
The Digital and Star-light uses a similar light magnification process. These devices use photocathodes that are responsible for converting infrared and dim light into protons to the electrode. Then electrodes are amplified, and the phosphor screen produces light flashes.
On the other side, the thermal imaging technique uses a heat-sensing mechanism. It senses the level of heat in viewing the target. Then depending upon the heat, it changes the color of the output image.
