Viewing-Zone-Angle-Expanded Color Electronic Holography System Using Ultra-High-Definition Liquid Crystal Displays With Undesirable Light Elimination

This paper describes a viewing-zone-angle-expanded color electronic holography system using ultra-high-definition liquid crystal displays (LCDs) with undesirable light elimination. The authors first investigate methods eliminating undesirable light, color aberration, and astigmatism. They then investigate spatio-temporal multiplexing methods to reduce system complexity. These investigations enable an electronic holography system to be constructed using 33 Mpixel LCDs. Experimental results show high-quality full-color 3D images with a diagonal size of 4 cm, viewing-zone-angle of 15 deg, and frame rate of 20 fps.
