  • Recording system for laser weapon simulator
    Patent number: 4198767
    Abstract: A recording system for use with a laser weapon simulator in which a laser am is transmitted through a window, bearing a target visible to the marksman, and onto a film record. A filter in the window blocks passage of the ambient light but passes the light from the laser beam and the back face of the window is provided with an illuminated, generally superimposed replica of the target. The replica of the target is photographed at the instant of firing by means of a camera, the shutter of which is electronically coupled to the weapon simulator, thereby permanently recording the position of the laser hit.
