Integrated light modulation architecture for multi-beam Retinal Scanning Display systems

摘要

This paper will start with a brief discussion of the high-resolution retinal scanning display (RSD) system architecture. The remainder of the paper will concentrate on the design and implementation of a miniaturized light modulation system used within a multi-beam RSD. Significant size and weight reduction, and good modularity are obtained using a custom designed, multi-channel AOM having the outgoing diffracted beam in-line with the incoming beams. Optical and mechanical design considerations of the acousto-optic based modulator and of the color combining module will be covered.
