Abstract:
The invention pertains generally to radio wave communications and more specifically to systems for distinguishing moving objects. The patent describes a moving target indicator for illuminating only those objects in motion. The invention consists of a phosphorous excitation source such as a defocused electron beam or ultraviolet light synchronized with a focused CO2 or similar laser for producing a thermal raster. By modulating the laser with image information, only the time changing intensities moving objects produce a visible phosphorescent image since only changing thermal temperature image patterns produce visible images.
