Laser warning receiver

Last updated

A laser warning receiver is a warning system used as a passive military or security 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 the Chinese Type 99 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.

Sentinel Photonics , a United Kingdom Ministry of Defence (MoD) spin-out company, is active in the development of laser warning receivers [4] . The company is known for LASERD MAX , a laser warning receiver designed to detect, classify, and geo-locate laser threats. The system has been associated with the emerging concept of Laser Intelligence (LasINT) , which involves the collection and analysis of laser activity to support situational awareness and threat assessment.
