Abstract
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 images with high resolution are reconstructed from the holographic display system with a red laser diode (LD), a green diode-pumped laser and a blue diode-pumped laser. The reconstructed color image can clearly be observed under the room light. The images exhibit good color expression. A phase-shifting holography system is also developed in order to record 3D color images, where phase of the reference light is shifted by changing fringe patterns displayed on the reflective LCD. Color image of the practical object are recorded as RGB fringe patterns by adopting a high-resolution color CCD. Clear RGB holograms are obtained from recorded fringe patterns by the phase-shifting method, and moving color images with high quality are reconstructed from the holograms by using the developed holographic display system.
