An information theory of image gathering

Abstract

Shannon’s mathematical theory of communication is extended to image gathering. The performance of image gathering, as well as of natural vision, is critically constrained by the realizability of the spatial-frequency response of optical apertures, the sampling passband of the photon-detection mechanism, and the signal-to-noise ratio. Hence, whereas Shannon… (More)
