16.3: Novel Polarization Conversion and Integration System for Projection Displays

Abstract

Abstract A novel polarization conversion and integration system based on an integrator rod and wide acceptance angle polarizing beam splitter cubes is presented. This system shows similar performance compared to the common polarization conversion system arrangement consisting of two lenslet integrators and a flat polarization conversion system. The proposed system offers low cost, high reliability and a compact illumination path for certain light engine architectures.
