64.2: Design and Characterization of a Compensator for High Contrast LCoS Projection Systems

Abstract

Abstract We describe the design and contrast measurement results of a high performance contrast enhancer for an LCoS‐based projection display that has these attributes: complete a/c‐plate compensation, accurate retardance targeting, excellent retardance magnitude and axis uniformity and environmentally durable. An overall system contrast of more than 4500:1 under f/2.4 cone illumination has been obtained.
