Popis:	We have been developing a new image sensor with a field emitter array and a high-gain avalanche rushing amorphous photoconductor (HARP) target, with the aim of using it in ultrahigh-sensitivity, high-resolution compact TV cameras. We fabricated and tested 256 × 192 pixel sensor with a pixel size of 50 × 50μm and its electron-beam focusing system consisting of permanent magnets. Experiments showed that the prototype sensor has both enough resolution for its pixel size and high sensitivity due to the HARP target, thus demonstrating its potential as a practical image sensor.
