  • Image sensing device
    Patent number: 8203112
    Abstract: A device includes an electron emission source array including a plurality of electron emission sources, a photoelectric conversion film disposed to face the electron emission source array, and an intermediate electrode provided between the electron emission source array and the photoelectric conversion film, and an intermediate electrode current detector that applies a positive potential, relative to a potential of the electron emission source array, to the intermediate electrode and detects a current flowing in the intermediate electrode.

  • Imaging apparatus and operation method of the same
    Patent number: 5488386
    Abstract: A photoconductive target having a transparent electrode layer and a photoconductive layer on a transparent substrate is disposed opposite to a group of integrated electron beam emitters having gate electrodes. A number of the electron emitters are activated to apply electron beams to the photoconductive target and the activated ones of the electron beam emitters are temporally changed over by an electron emitter selector circuit and a gate selector circuit. Signal charge generated and stored in the photoconductive layer is read. A time-series electric signal corresponding to a spatial distribution of the incident light is generated. A thin imaging apparatus suitable for a larger area is thus provided.
