Optical Decoder.
Abstract
This document describes an optical device, for modulating radiation from an extended object by means of a pattern encoded reticle, in which said radiation is converted by a single photo detector to an electrical signal which drives a light emitting diode from which the light train is re-modulated by the same reticle and then sensed by a charge transfer device to produce as a decode output the image of the extended object. This optical imaging device makes use of the Fellgett or multiplex advantage to produce high resolution, high sensitivity images. (Author)
