Full-Color Holographic Display with Wide Visual Field and Viewing Zone

摘要

A time-sharing holographic color display system is developed using a high-resolution reflective liquid-crystal display (LCD) panel that consists of a 1920x1080 array of square pixels with width of 8.1 micron. Red, green and blue high-resolution images are reconstructed from the holographic display system with a red laser diode (LCD), a green diode-pumped laser and a blue diode-pumped laser. The reconstructed color images can clearly be observed under the room light. The images exhibit good color expression. High-quality color images of the practical object are reconstructed from the holograms by using the developed holographic display system. The viewing zone or the visual field of the holographic display is enlarged by adopting a multi-channel LCD modulator. 3-D full-color images are reconstructed in the wide visual field. Viewing zone angle or visual field angle of color images can be enlarged up to about 20 degrees by adopting a 6-channel LCD modulator.
