As a supplementary light source, infrared laser is applied to night vision for security purpose, of which principles are the same as identification and processing of images by eyes. Near infrared laser irradiation may produce reflected light on the surface of articles.

Reflected light is to be further captured by infrared camera establish an automatic and intelligent night-vision lighting system based on client based intelligent platform. Night-vision lighting products for near infrared diode lasers have been widely applied to such fields as railway detection, intelligent traffic monitoring, prevention of forest fire, frontier defense, coast defense and urban construction.
