Abstract
Systems and methods of separating the input light path from the output light path of a scanning mirror in a laser projector system while keeping the overall footprint of the laser projector system to a minimum. The system includes a scanning mirror, an optical engine, and an input/output (I/O) separator disposed between the optical engine and the scanning mirror to direct light from the optical engine towards the scanning mirror along an input path and to direct light reflected from the scanning mirror along an output path. The I/O separator, disposed to intersect both the input and output paths, can be implemented as a prism or a combination of a polarizing beam splitter and a quarter wave plate.
