ABSTRACT:
Apparatus and method are disclosed directed to a real time, electro-optical light projection system, wherein at least one selected target is displayed on a high resolution mini-raster, differentiated from a coarse resolution base raster background. A full color display of the target on a full color background is provided with three cathode ray tubes in association with corresponding liquid crystal light valves. Alternatively, a single cathode ray tube and an associated liquid crystal light valve are used to display the target monochromatically against a monochromatic background.
