AUTOMATIC LASER ADJUSTMENT SYSTEM FOR SMALL ARMS WITH IDENTIFICATION OF GAMES PARTNER Russian patent published in 1998 - IPC

FIELD: small arms. SUBSTANCE: electromechanical device automatically adjusts laser transmitter attached to rifle barrel by means of bolts for subsequent use by serviceman in military games. Rectangular hollow housing is positioned horizontally, and end face cover is hinged out upwards opening the liquid crystal display and keyboard of the control panel. Sliding frame is withdrawn in horizontal direction from the base unit located inside the casing. Rifle barrel is supported by armory post installed on base unit, and trigger bow or contact cartridge is installed on the frame in a clamp. The clamp has knobs for adjusting the weapon in azimuth and elevation which allows the serviceman to take aim at the reticule image. Optical unit is installed in the front part of base unit and has a lens and a beam splitter, which is transparent for infrared light from laser transmitter and reflects visible light. Illuminated reticule is located inside the optical unit below the laser beam axis. Beam splitter is positioned before the lens at angle of 45 deg so as to project the reticule image through lens on infinity. Beam position detector in the optical unit receives the laser beam and produces an error signal corresponding to the shift of the point of laser beam reception relative to reticule image. The control unit circuit is connected to the adjusting head that is mechanically linked with the back end face of the transmitter bolted to the rifle. This circuit makes the adjusting head repeatedly trigger the laser in laser transmitter. Using the error signal, the circuit makes the adjusting head rotate independently the wedge-shaped prisms in the laser transmitter so as to deflect the laser beam in azimuth and elevation until it is essentially matched with the weapon sight line. EFFECT: enhanced accuracy of adjustment. 20 cl, 10 dwg
