MICROCHANNEL PLATE IMAGE INTENSIFIERS AND METHODS OF PRODUCING THE SAME

Abstract: image intensifier systems incorporating a microchannel plate (mcp) and methods for producing the same are disclosed. a device is disclosed that includes a first substrate having a radiation-receiving first surface and an opposed second surface through which electromagnetic radiation is transmitted. a second substrate is coupled to the first substrate to define a vacuum cavity therebetween having electron-emitting photocathode is disposed therein. a microchannel plate (mcp) is disposed within the vacuum cavity and defines microchannels extending from an input end to an output end. each of the microchannels is configured to generate/amplify electrons in response to the electrons received photocathode. the imaging array can include a plurality of metal plates connected to capacitors and configured to collect electrons from the mcp to produce a digital image responsive to electromagnetic radiation received at the first substrate and converted to electrons by the photocathode and multiplied by the mcp.
