PIN MATRIX LIGHT VALVE STUDY.
Abstract
The purpose of this study and investigation was to determine the feasibility and practicality of utilizing a pin matrix light valve as a large screen display device. Because of the lack of availability of wire mosaics (pin matrix arrays) having suitable mechanical and vacuum characteristics, the possibility of making a light valve device of adequate resolution is low without more work on the mosaic fabrication process itself. This conclusion is based on the practical problems encountered in trying to procure suitable large area faceplates. In this program several wire mosaics were purchased and evaluated, faceplate assemblies were fabricated and problems associated with constructing a sealed pin matrix tube were investigated. In addition, the wetting properties of selected fluids were studied and a method developed for producing and measuring thickness of fluid films. Optical system improvements were suggested and evaluation of the system's inherent limitations is presented. (Author)
