1. 介绍了一种基于视差射线重建的实时彩色三维显示系统。该显示系统由全息光学元件组成的全息屏和作为空间光调制器的数字微镜器件组成。该系统的主要特点是可以显示可视角度在56度以内的全息视频系统等动画彩色3D图像。我们提出并实现了一种使用双显示设备的增强型3D显示系统。实验结果表明，采用双装置系统可以扩大观测角度和观测区域。为实时彩色三维显示系统，提出并实现了获取真实三维物体光线数据的多视点摄像系统。实验系统由9台COMS摄像机和FPGA图像处理器组成。在该系统中，能够观察到重建的三维图像的时间约为1秒。如果摄像机系统由9个CMOS摄像机和9个图像处理器组成，每个图像处理器控制1个摄像机，则可以减少能够观察的时间。

1. The real-time color 3D display system based on the reconstruction of parallax rays was described. This display system consists of a holographic screen constituted of holographic optical elements and a digital micromirror device as an spatial light modulator. The main feature of this system is that can display animated color 3D images such as the holo-video system with viewing angle within 56 degrees.2. We have proposed and implemented an enhanced 3D display system using double display devices. Experimental results shows that it is possible to widen the viewing angle and the viewing zone using the double-device system.3. We have proposed and implemented the multiview camera system to obtain the ray data of real 3D objects for the real-time color 3D display system. The experimental system consists of 9 COMS cameras and the image processor using FPGA. In this system, the time to be able to observe a reconstructed 3D image is about 1 second. If the camera system consists of 9 CMOS cameras and 9 image processors, and each image processor controls 1 camera, the time to able to observe can be reduced.
