REDUCING STRAY LIGHT IN BEAM STEERING SYSTEMS USING POLARIZATION GRATINGS

This disclosure describes systems, methods, and apparatus for reducing stray light in a non-mechanical beam steering or light angle alteration application. A nonmechanical beam steering assembly, including polarization-controlling switches and polarization gratings, can be followed by or preceded by...
