我们已经构建了一个简单的彩色电子全息系统，具有良好的性价比。它使用图形处理单元（GPU）和液晶显示器（LCD）投影仪。GPU的结构适合于计算计算全息图（CGH）。GPU的计算速度比中央处理器快约1,500倍。LCD投影仪是一种廉价、高性能的CGH显示设备。它有高清晰度液晶面板的红色，绿色和蓝色。因此，它可以很容易地用于彩色电全息。对于由1,000个点组成的三维物体，我们的系统成功地以每秒30帧的速度实现了实时彩色全息重建。(C)2009年美国光学学会
We have constructed a simple color electroholography system that has excellent cost performance. It uses a graphics processing unit (GPU) and a liquid crystal display (LCD) projector. The structure of the GPU is suitable for calculating computer-generated holograms (CGHs). The calculation speed of the GPU is approximately 1,500 times faster than that of a central processing unit. The LCD projector is an inexpensive, high-performance device for displaying CGHs. It has high-definition LCD panels for red, green and blue. Thus, it can be easily used for color electroholography. For a three-dimensional object consisting of 1,000 points, our system succeeded in real-time color holographic reconstruction at rate of 30 frames per second. (C) 2009 Optical Society of America
