Q:The working principle of the camera with infrared light

Second, the infrared camera imaging principle In the night vision monitoring system, the conventional approach is to use the visible light, but this way there can not be hidden, easy to monitor the target and other shortcomings, so use less; the current hidden, scientific night vision monitoring Is the use of infrared camera technology. Infrared camera technology is divided into passive and active. Passive infrared camera technology is the use of any substance in the absolute zero (-273 ℃) are more than infrared radiation, the higher the temperature of the object, the more infrared radiation. The most typical of the cameras made with this principle is the infrared camera, but this special infrared camera is expensive and therefore limited to military or special occasions. The active infrared camera technology is the use of infrared light radiation "lighting" (mainly infrared light), the application of ordinary low-light black and white camera, color to black and white camera or infrared low-light color camera, feel around the scene and the environment reflected back to the infrared light to achieve Night vision monitoring. Active infrared camera technology is mature, stable, become the mainstream of night vision monitoring.
