A CD-R system for recording computer-generated holograms

Abstract

To display 3D images on a computer-generated hologram, you need to have a very high resolution hologram-recording system. We developed a CD-R (Compact Disk-Recordable) drive to record CGH data on CD-R disks, that have a high resolution and a dot size of 1.5μm. By using this drive, it is possible to make holograms inexpensively in a short-time without the need for special environments, such as dark rooms, clean rooms, etc. The drive realizes desktop holograming that can handle all CGH process including model making, hologram calculations, and hologram recordings on a personal computer. In this paper, we describe the system and discuss the hologram-calculation method adapted for CD-R disks.
