本文提出了一种分时全息彩色显示系统，它采用了一种高分辨率的反射式液晶显示器（LCD），由1920 × 1080的宽8.1微米的正方形像素阵列组成。利用红光激光二极管（LD）、绿色激光器和蓝光激光器组成的全息显示系统，再现了高分辨率的红、绿色和蓝色图像。在室内光照下，可以清晰地观察到重建的彩色图像。图像表现出良好的色彩表现力。为了记录3D彩色图像，还开发了相移全息系统，其中通过改变反射式LCD上显示的条纹图案来移动参考光的相位。采用高分辨率彩色CCD，将实际物体的彩色图像记录为RGB条纹图。用相移法从记录的条纹图中获得清晰的RGB全息图，并利用研制的全息显示系统从全息图中再现出高质量的彩色运动图像。
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.
