Abstract
The present invention comprises a method for detecting photons and generating a representation of an image. A photocathode receives photons from an image. A power supply to the photocathode is gated such that the photocathode is switched between an on state and an off state. The photocathode discharges electrons in response to the received photons while the photocathode is in the on state. 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 screen receives the secondary electrons and displays a representation of the image.
