摘要：An image sensor has been developed that consists of an X-Y-matrix field emitter array (FEA), a mesh electrode, and a high-gain avalanche rushing amorphous photoconductor (HARP) target, each of which is set closely facing one another. Investigation of its fundamental driving characteristics in a vacuum chamber showed that TV images are produced when the matrix FEA consists of 50×50 elements, that images are picked up with high sensitivity due to the HARP target, and that the output signal current is not affected by fluctuations in the emission current from the FEA under ordinary lighting conditions. Applying appropriate voltages to the mesh electrode improved the resolution. This image sensor will enable the development of super-high-sensitivity and ultrahigh-definition TV cameras.
