摘要
计算全息技术的快速发展使得全息电视、全息电影成为可能.许多研究者正在致力于开发的电子全息三维显示系统的最关键的技术之一就是提高计算全息技术的运算速度.由于计算全息技术所需要的计算量很大,使用一般计算机无法以帧频速率实现全息图的计算,因此研究者们在提高全息图的计算速度方面进行了大量的研究工作.在主要调查研究使用硬件加速的方法来提高全息图计算速度的基础上,论述了其研究现状以及未来的发展动态.
It is possible to fullfil a holographic television and movie with the rapid development of Computer-Generated Holography （CGH）. Many researchers make effort to develop new kinds of electroholography 3D display system, and raising the calculating speed of CGH is one of the most important factors. Because of the CGH＇ s enormous computational time, it is difficult for a general computer to reach the computational ability at video rate. Researchers have done a lot of work to accelerate the calculation speed. The present situations to increase the calculating speed by the hardware approaches are summarized, and the research trend in the future is discussed.
