  • Lead computing sight
    Patent number: 5127165
    Abstract: The gun sight comprises a cathode ray tube (21) to generate an aiming image and optical means (22,23) to project said generated image into a line of sight through the gun sight. Velocity of movement of the gun sight is sensed by gyros and in response thereto the cathode ray tube (21) generates an aiming image at a location displaced from a sight-stationary position by an amount dependent on the velocity and direction of movement of the gun sight and a predetermined target range.
