Holographic video system using Fourier transform method adapted to 2-dimensional and 3-dimensional data calculation

Abstract

A holographic video system, displaying computer generated Fourier transform hologram is described. The method of Horizontal Parallax Only (HPO) Fresnel CGH is well known. HPO computer generated Fourier transform hologram is basically 2-dimensional hologram. To expand a HPO computer generated Fourier transform hologram algorithm based on the ray tracing is introduced. This algorithm can possibly reduce CGH data amount and CGH calculation time. The experimental result is included, and it shows the reduction of CGH data amount and CGH calculation time. One extra advantage compared with Fresnel CGH is described as well.
