Abstract
A novel optical system and method for coupling and mixing a plurality of beams which may originate from different optical sources and may be of different colors. There is provided deflection and steering of light beams with automatic (self-aligning) Bragg matching over a large beam deflection range which is not limited by the Brass condition. There is also provided a novel method of spatial light filtering and modulation, image color conversion, bidirectional beam interconnection for optical communication and combining and locking of laser sources.
