Abstract
A multilayer electronic imaging module and sensor system incorporating a micro-lens layer for imaging and collimating a received image from a field of regard, a photocathode layer for detecting photons from the micro-lens layer and generating an electron output, a micro-channel plate layer for receiving the output electrons emitted from the photocathode in response to the photon input and amplifying same and stacked readout circuitry for processing the electron output of the micro-channel plate. The sensor system of the invention may be provided in the form of a Cassegrain telescope assembly and includes electromagnetic imaging and scanning means and beam-splitting means for directed predetermined ranges of the received image to one or more photo-detector elements which may be in the form of the micro-channel imaging module of the invention.
