Abstract

We have applied the graphics processing unit (GPU) to computer generated holograms (CGH) to overcome the high computational cost of CGH and have compared the speed of a GPU implementation to a standard CPU implementation. The calculation speed of a GPU (GeForce 6600, nVIDIA) was found to be about 47 times faster than that of a personal computer with a Pentium 4 processor. Our system can realize real-time reconstruction of a 64-point 3-D object at video rate using a liquid-crystal display of resolution 800x600.

摘要

我们已将图形处理单元（GPU）应用于计算机生成全息图（CGH），以克服CGH的高计算成本，并将GPU实现的速度与标准CPU实现的速度进行了比较。结果发现，GPU（英伟达GeForce 6600）的计算速度比配备奔腾4处理器的个人计算机快约47倍。我们的系统可以使用分辨率为800x600的液晶显示器以视频速率实时重建64点三维物体。
