Paper Abstract

Video surveillance is a powerful tool for law enforcement and security agencies. Recent improvements in the efficiency and cost of high power IR lasers have facilitated their use for auxiliary or flood lighting in surveillance video systems. IR lighting is especially useful for covert security situations and for situations where extra flood lighting would be objectionable. This inclused theaters, libraries, gas stations, etc. The application of IR laser lighting creates special engineering problems in the areas of eye safety, laser speckle, and video camera compatibility. This paper discusses tradeoffs performed in the design of an IR laser illumination system and presents sample imagery from a prototype system.
