Abstract
An active optical tracking system for air-to-air type missiles of relatively small dimensions having a pulsed laser transmitter operating through a gimbaled mirror system and a reflection receiving system connected to the guidance and control unit of the missile to direct it to a target.
Claims1
Optical radiation transmitting means for active optical tracking systems in missiles comprising:
- a base, a post mounted on the base having an aperture therethrough, parallel to the longitudinal axis of the post;
- an inner gimbal mounted on one end of the post including a yoke, a pin extending from the yoke and a movable gimbal ring;
- an outer movable gimbal ring connected to the inner gimbal ring including a pin extending through the inner gimbal ring;
- a diverging lens mounted on said outer gimbal ring;
- a first mirror means mounted on the yoke pin adapted to receive radiation passing through said aperture;
- a second mirror mounted on the inner gimbal adapted to receive radiation from the first mirror and a third mirror mounted on the outer gimbal pin adapted to receive radiation from the second mirror and direct said radiation through the diverging lens.
