Abstract

Contrast in large flight-simulator screen displays can be significantly enhanced, and power requirements much reduced, by concentrating projected light into a small solid angle around the viewer's line of sight. This is accomplished by the use of a multiplicity of holographic optical elements, all of the same efficiency and of a size below the resolving power of the viewer's eye. If the number of elements is very large, however, automated hologram replication becomes essential. This paper describes the development of a high-gain projection screen consisting of over 10 million holographic elements embossed in aluminized mylar. The design of the holographic master and the replicating technique are discussed.
