Abstract
An alignment and stabilization system that automatically aligns and stabilizes off-gimbal electro-optical passive and active sensors. The system dynamically boresights and aligns one or more sensor input beams and an output beam of a laser using automatic closed loop feedback. The system includes a reference light (photo) detector, or reference source, disposed on a gimbal, off-gimbal optical-reference sources, or corresonding photodetectors, and two alignment mirrors. Aligning the one or more sensors and laser to the dynamically steered null of the on-gimbal reference photodetector (or reference source) is equivalent to having the sensors and laser mounted on the stabilized gimbal with alignment mirrors providing a common optical path for enhanced stabilization of the sensors and laser lines of sight.
