Electronics Development for Enhancement of High Resolution, Eight Inch Display.

Abstract

This report documents the work performed to further enhance the performance of the 8-Inch High Resolution Display previously developed for Night Vision Laboratory under U.S. Army Contract DAAK02-72C-0333. The work performed followed the recommendations made in the previous Final Report, ER 60803-08, and communication with Night Vision Laboratory. A CRT with a P43 phosphor and matching high density narrow band optical filter was used to increase contrast ratio. The CRT was operated with an anode voltage of 15KV. An AGC amplifier was designed to detect peak black and peak white video to improve the dynamic range of the picture. A vertical stigmation circuit was employed to merge the raster lines and thus increase the smoothness of the raster. Though the measured results showed a significant improvement in creating a flat field, empirical observer reactions were not as favorable. (Author)
