Scanning system for optical transmitter beams

摘要

A system for rapidly scanning a remote field of regard with transmitter laser beams comprises an optical system having a focal plane, a plurality of lasers capable of being sequentially fired, and a like number of optical fibers coupled at one end to the respective laser outputs. The opposite fiber ends lie in the focal plane of the optical system and are aligned in the direction of the height of the field of regard. The beams move rapidly across the width of the field of regard simultaneously with sequential operation of the lasers, thus illuminating the entire area of interest in a minimum of time.
