Polarization Conversion System Using a Polymer Polarization Grating

摘要

We describe a new Polarization Conversion System (PCS) concept, particularly well suited for pico-projectors, employing a polymer polarization grating thin-film, fly-eye lens, and louvered halfwave plate. We demonstrate improved polarization-conversion in the PG-based PCS, leading to enhanced brightness (12%) and color-uniformity (20%) as compared to a conventional PBS-based PCS.
