The performance of a novel three-dimensional (3-D) image projector with polarized glasses is analyzed that consists of polymer-dispersed liquid-crystal light valves and a Schlieren optical system. The cross-talk and the extinction-ratio characteristics of the new 3-D display have been calculated by means of Mueller matrices. Quantitative analyses show that the proposed display achieves small cross talk of less than 1% and sufficient extinction ratio almost the same as the light valve.

Key words: three-dimensional image display, spatial light modulator, projector, polymer-dispersed liquid crystal, cross talk, extinction ratio
