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.
