ABSTRACT:
A marksman training system is disclosed as including a translucent diffuser arget screen adapted for producing a bright spot on the rear surface of the target screen in response to receiving a laser light beam on the front side of the target screen that was fired from a laser rifle. A television camera scans the rear side of the target screen and produces a composite signal representing the position of the light spot on the rear surface of the target screen, after which the composite signal is broken into its X and Y Cartesian component signals and a video signal by a conventional television signal processor. The X and Y component signals consists of numbers of pulses which are shaped and then uniquely counted by digital counters, stored in registers, and converted to a pair of proportional analog voltage signals by digital-to-analog converters. A target recorder reads out the pair of analog voltage signals as a point, the location of which is comparable to the location on the target screen where it was hit by the laser light beam.
