Abstract
Abstract Imaging apparatus for an electronic imaging camera responds to a scene image by converting photons into electrons representative of the scene image. A microchannel electron multiplier, including a microchannel plate, having an output surface at its output side is coupled to receive the electrons representative of the scene image and operates to intensify the electron representation of the scene image. A charge transfer device in the form of a charge coupled device (CCD), directly coupled to the output surface responds to the electron output to produce an electric signal representation of the scene image received by the camera. The electric signal representation is read out of the CCD by clock voltages and may have the form of a serial picture sample output. A signal processor may be provided to develop a video output from the sample output.
