1. An intensified solid-state imaging sensor, comprising:

  • a. a photo cathode having an input side for receiving light from an image, and an output side from which electrons produced by the photo cathode exit;

    b. a microchannel plate having an input surface positioned adjacent to the output surface of the photo cathode, an output surface from which an increased number of electrons exit, and a plurality of channels formed between the input surface and the output surface;

    c. a first electrical connection for applying a first biasing voltage between the photo cathode and the microchannel plate;

    d. a solid-state imaging device having an electron receiving surface, positioned adjacent to the output surface of the microchannel plate, for receiving the increased number of electrons output from the microchannel plate, and an output for outputting an intensified image signal;

    e. a second electrical connection for applying a second biasing voltage between the microchannel plate and the solid-state imaging sensor;

    f. a vacuum body holding the photo cathode, microchannel plate and solid-state imaging device together as a unit; and

    g. an insulating layer separating the output surface of the microchannel plate and the electron receiving surface of the solid-state imaging sensor.
