| Abstract(in English) | An image sensor is described that uses a field emitter array (FEA) and a high-gain avalanche rushing amorphous photoconductor (HARP). An experimental device was constructed of an FEA with 50×50 elements, a mesh electrode with an aperture ratio of about 50%, and a 2-μm-thick HARP target. The electrode and target were set facing one another. Investigation of the fundamental characteristics of this device in a vacuum chamber showed that it can pick up images satisfactorily. Using the HARP target resulted in high sensitivity, and the temporal fluctuation and spatial variation in the emission currents obtained from the FEA had almost no effect on the current of the output signal. Investigation of potential packaging structures and sealing methods showed that a glass-capsule-sealed structure, which was fabricated experimentally, is a promising one for practical applications. |
