MEMORY DISPLAY FOR PULSE ILLUMINATED IMAGES.
Abstract
The objective of this program was the research and development of a high definition meshless storage and display screen based on the use of a thin SEBIC (sustained electron bombardment-induced conductivity) film as a control layer for an adjacent dc electroluminescent film. The feasibility of such a meshless screen was demonstrated for the first time. Data are presented on several tubes incorporating meshless screens which exhibited storage, integration, and controlled erasure. Stored resolutions greater than 500 line pairs/in., writing speeds in excess of 500,000 in./sec., and a stored brightness of 1/2 ft - L were measured. The problems encountered in fabricating such a screen and the investigations which led to their solution are described in detail. This advance, which demonstrates the ability to sense, store and display imaging information with near photographic quality in real time on a reusable medium (electronic photography), represents the attainment of a long standing major technological goal in the field of image detection and display.
