What distinguishes active infrared night vision equipment from passive in that technology?
Active night vision system: It uses a low-light camera or a low-light camera to capture the infrared light reflected by the target and transform it into a video signal on the monitor screen. Near-infrared light sources used in this system include infrared LEDs, infrared lamps, and near-infrared lasers. Active infrared night vision equipment falls under this category.
There are two types of passive night vision systems. One uses only very weak natural light, such as moonlight, starlight, and night sky light, to magnify and enhance the visual purpose; this sort of night vision equipment is also known as a low-light night vision system. The other method involves using a far-infrared sensitive detector to find the target's heat radiation. Thermal imager is another name for this kind of night vision gadget.
