Electro-holography is a promising display technology that can reconstruct a photorealistic three-dimensional (3D) movie; however, it is yet to be realized practically owing to the need for enormous calculation power. A special-purpose computer for electro-holography, namely HORN, has been studied for over 20 years as a means to solve this problem. The latest version of HORN, HORN-8, was developed using field programmable gate array (FPGA) technology. Initially, a circuit for amplitude-type electro-holography was implemented in HORN-8; however, implementation of phase-type electro-holography has remained an issue. In this paper, the development of new version of HORN-8 and its cluster system, which achieved a real-time reconstruction of a 3D movie with point clouds comprised of 32,000 points for phase-type electro-holography, was reported.
电子全息术是一种很有前途的显示技术，它可以重建逼真的三维（3D）电影；然而，由于需要巨大的计算能力，它尚未在实际中实现。作为解决这一问题的一种手段，用于电子全息术的专用计算机——即HORN，已经研究了20多年。HORN的最新版本HORN-8是使用现场可编程门阵列（FPGA）技术开发的。最初，在HORN-8中实现了用于振幅型电子全息术的电路；然而，相位型电子全息术的实现仍然是一个问题。本文报道了新版本的HORN-8及其集群系统的开发情况，该系统实现了用由32000个点组成的点云对相位型电子全息术的3D电影进行实时重建。
