Real-time Three-dimensional Display Using a Holographic Optical Element

Abstract

A display system requiring no special glasses is a useful technology for three-dimensional (3-D) images. The lenticular display system has such demerits as having a non-planer screen and blurred images. In this paper, a newly developed, 3-D real-time display with a holographic optical element (HOE) is described. This simple 3-D display can avoid problems of lenticular systems. The advantage of the screen HOE is that the number of presented views is much greater that of an equivalent lenticular display, because the screen HOE can multiplex pixels both horizontally and vertically to display lateral views. This screen HOE can be made more easily and smoothly than an electron beam recording. The trial screen HOE is 4“×5” and consists of 128, 000 holograms. Therefore, the image size measures approximately 4“× 5”, and the resolution is 200×160 pixels×4 views.
