Stimulated scanning infrared imaging system

Daniel Preston Smith; Robert David Lillquist

A scanning infrared display system capable of variable magnification and high spatial resolution measures the emitted infrared radiation caused by the scanning of a highly collimated energy source beam on the surface to be imaged. The resulting infrared emissions are collected with a high sensivity stationary detector. The display image is formed on a CRT by scanning the object with a raster pattern in synchronization with the CRT and modulating the Z axis CRT potential (brightness) with the infrared detection signal.
