Abstract
The present invention comprises a photon detector and image generator, which includes a photocathode that receives photons from an image. The photocathode discharges electrons in response to the received photons. A microchannel plate with an unfilmed input face and an output face receives the electrons from the photocathode and produces secondary emission electrons which are emitted from the output face. A display receives the secondary electrons and displays a representation of the image. The photon detector and image generator has a lifetime of more than 7,500 hours.
