Infrared night vision devices are divided into active and passive types. What are the differences between the two?

Active night vision systems utilize near-infrared light as a light source to illuminate the target, such as infrared LEDs, infrared lamps, and near-infrared lasers. A low-light or low-light camera receives the infrared light reflected from the target and converts it into a video signal, which is then simultaneously displayed as an image on a monitor screen. This type of night vision device is called an active infrared night vision device. Passive night vision systems have two types: one utilizes...
