Moving target practice firing simulator

摘要

An electro-optical system for weapons training, consisting of a low-power eye-safe laser beam simulating the weapon's fire, a realistic moving target scene projected by a moving picture projector or slide projector onto a screen, a laser beam hit detector based upon a second projector, and a display board for displaying the hits and attempts of each trainee. Multi-station operation is accomplished by a digitally multiplexed time sharing system which allows each laser beam to fire only during a discrete time interval regulated by encoder pulses transmitted by radio. The laser beam detector is synchronized with the film of the target projector and acts as an annotated mask, this mask being opaque except for transparent areas corresponding to the target areas projected by the projector. A properly aimed laser beam will pass through the transparent area of the mask and be counted as a hit by the hit detector.
