ANALYSIS OF INTRINSIC PHOTOCONDUCTORS USED FOR INFRARED IMAGING PURPOSES

Abstract

Infrared imaging systems have been proposed in which one photocell can detect many different resolution elements of the image by novel means of scanning. In previous systems one photocell processes the information of one resolution element at any one instant of time. This paper attempts to analyze and evaluate different systems. The discussion begins with an analysis of a photoconductive cell. The reasons for the choice of photoconductive cells for infrared are discussed. The signal-to-noise ratio is derived for weak signals under the assumption that the current noise is predominant. Changes in cell dimensions and illumination patterns are investi gated. The cell analysis is applied to imaging systems. Sequential scanning systems, mosaic systems, and reticle scanning with orthogonal functions are treated.
