RANDOM ACCESS LIGHT VALVE STUDY.

Abstract

The purpose of this study was to determine the feasibility of producing a random scan light valve by using a cathode-ray tube with a wire mosaic faceplate to transfer the charge pattern on the inside of the tube to the outside where it would interact with a thin fluid film and thereby cause a change in the surface flatness of this film. In this study program, the variations in the surface flatness were viewed with a Schlieren optical system which projected a bright image of the variations in the surface flatness to a viewing screen. A breadboarded model of a recommended system was constructed and its performance was analyzed. Test results indicated that a full-size system based on this principle is feasible and will provide the desired characteristics of brightness, resolution, and random scan. (Author)
