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.

Image sensing device

An imaging apparatus includes an electron emission array having electron sources arranged in matrix form, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film, wherein the control and drive circuit is further configured to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film in any one or more blanking periods excluding both a blanking period immediately following the given video signal output period and a blanking period immediately preceding a next video signal output period in which the one or more horizontal scan lines will be selected next time.

Imaging apparatus having electron source array

Electron-emissive drive units of electron-emissive elements capable of being arranged with a smaller pitch. FET and emitter array units exist in matrix element areas partitioned by a control wiring and data wiring. An exemplary unit is composed of four emitter arrays. The control wiring and data wiring are driven by first and second drive circuits, respectively. Corresponding arrays between units are connected by selection wiring and driven by a third drive circuit. The third drive circuit drives each unit of data wiring every time the drive circuit sequentially drives the four units of control wiring, and the emitter array drive circuit drives each emitter array selection wiring every time the drive circuit sequentially drives the three units of data wiring. Electrons can be emitted in units of arrays smaller than the unit.

Electron emissive element and display element

An imaging apparatus includes an electron emission array having electron sources arranged in matrix form and having a plurality of horizontal scan lines, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more of the horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film to produce a video signal, wherein the control and drive circuit is configured to cause the electron sources included in unselected one or more horizontal scan lines not selected in the given video signal output period to emit electrons toward the photoelectric conversion film in a blanking period immediately preceding the given video signal output period.

An imaging apparatus includes an electron emission array having electron sources arranged in matrix form and having a plurality of horizontal scan lines, a photoelectric conversion film opposed to the electron emission array, and a control and drive circuit configured to select one or more of the horizontal scan lines in a given video signal output period and to cause the electron sources included in the selected one or more horizontal scan lines to emit electrons toward the photoelectric conversion film to produce a video signal, wherein the control and drive circuit is configured to control electron emission of the electron emission array in a blanking period in response to a signal level of the video signal produced in the given video signal output period.

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.

Imaging apparatus and operation method of the same

A charged-particle beam tube having an envelope of a dielectric material and a pattern yoke formed on the inner surface of the envelope. The pattern yoke has a pair of horizonal deflection electrodes and a pair of vertical deflection electrodes arranged alternately. The horizontal deflection electrodes have a greater circumferential width than the vertical deflection electrodes. The horizontal and vertical deflection electrodes are supplied with different bias voltages.
