Military use infrared systems
for night operation. Infra red systems used in military are provided with
additional infra red illuminators. The advantages of these systems are low
background contrast and limited range. In these systems, very fast and highly
sensitive infra red detectors and electro-optical scanners are used. Display of
infra red systems is very much similar to TV display. Two popular military infra
red systems are infra red line scanner system and forward looking infra red
system. Infra red line scanner system is used for the production of imagery of
the terrain over flown. Here scanning of ground is carried out in narrow strips
at right angles to the line of flight of the motion of aircraft followed by
recording on a film. Forward looking infra red systems are often used with
radar and can perform multi sensor operations. Some other infra red systems
used in military are cyclone airbone infra red reconnaissance system, TA-7M2
aerial camera, FFV UNI reconnaissance pod, vinten airbone camera, Minisan
camera, pave spike video film recorders, return beam vidicon camera, laser beam
image reproducer and laser radar recorder.
