Abstract

Novel kinds of rear-projection viewing screens are described. The light incident on each part of the screen is deflected and scattered by a prescribed amount, so that the picture presented to the viewer is optimized. In addition, the amount of light needed can be minimized. The screens are produced in dichromated gelatin by photographic techniques with coherent light. In one case, a hologram is formed that allows any kind of characteristic to be produced but suffers from less than 100% efficiency; in the other case, an interferometric exposure with appropriate development results in a screen with almost ideal characteristics for a short-focal-length viewer, such as a microfilm reader. The processing techniques and results are discussed, and an attempt is made to explain the unusual characteristic of the second kind of screen.
