Abstract
A real-time color holography system is developed using a high-resolution reflective liquid-crystal display (LCD) panel that consists of a 1400x1050 array of square pixels with width of 10.4 micron. Red, green and blue images with high resolution are reconstructed from the holography system with a red laser diode (LD), a green laser and a blue lightemitting diode (LED) as the reference light. The reconstructed color image with high resolution can clearly be observed under the room light. Directly viewable color images with both eyes or images in the wide visual field are reproduced using the 3-channel LCD modulator. The viewing-zone angle or the visual-field angle of the 3-D display system can be expanded up to about 9 degrees using three LCD panels. Fringe patterns for a practical object are also recorded by a high-resolution CMOS sensor, and a moving image of the object is reproduced from the fringe patterns by the developed holographic display system.
