linescan

linescan
The device for scanning successive narrow strips of the ground to produce a picture of the terrain over which the aircraft is flying. An active optical linescan uses an airborne illuminating device such as a laser, whereas a passive optical linescan uses natural daylight and infrared radiation from the ground.
