Laser warning receiver




A laser warning receiver is a type of warning system used as a passive military defence. It detects, analyzes, and locates directions of laser emissions[1] from laser guidance systems and laser rangefinders. Then it alerts the crew and can start various countermeasures, like smoke screen, aerosol screen (e.g. Shtora), active laser self-defence weapon with laser dazzler (LSDW, used on Type 99 China main battle tank[2]), laser jammer, etc.


Detectors used in LWR are usually based on a semiconductor photodetector array, which is typically cryogenically or thermal-electric cooled. Sometimes avalanche photodiodes (APD), photoconductivity, photoelectromagnetic, or photodiffusion devices are used even without cooling.[3] Some devices detect only the main beam of foreign lasers while others detect even scattered rays.
