Real-time 3-D Color Display Using a Holographic Optical Element

Abstract

A display system requiring no special glasses in a useful technology for three-dimensional (3-D) images. The lenticular display system has demerits such as a non-planar screen and blurred images. In this paper, a new 3-D real-time color display with a holographic optical element (HOE) is described. This simple 3-D display can improve the above-mentioned problems. The advantage of the HOE screen is that the number of presented views is much greater than the number of presented views of an equivalent lenticular display, because the HOE screen can multiplex pixels both horizontally and vertically to display lateral views. This color screen can be made easily and smoothly in the same way as the monochrome screen. The trial HOE screen is 4″×5″ and consists of 384, 000 holograms Therefore, the image size measures approximately 4″×5″, and the resolution is 200×160 pixels×4 views×3 (RGB).
