摘要:
An image intensifier includes a photocathode (11) with a face plate (22). A conductive layer (24) is disposed outwardly from the face plate (22). A grounded conductor (16) is electrically coupled to the conductive layer (24) and grounds the conductive layer (24).
摘要:
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 is located no more than about 125 microns from the photocathode. The microchannel plate has an unfilmed input face and an output face that receives the electrons from the photocathode. The microchannel plate produces secondary emission electrons which are emitted from the output face. A screen receives the secondary electrons and displays a representation of the image.
