Abstract :
In a new application of field emitter arrays (FEAs), a unique, ultrahigh-sensitivity, flat image sensor that consists of an FEA and an avalanche-mode photoconductive target is proposed. We have been working to develop highly sensitive camera tubes with a high-gain avalanche rushing amorphous photoconductor (HARP) target. Although our latest HARP tube is about 100 times as sensitive as a conventional solid-state image sensor, it suffers from drawbacks related to its length (about 100 mm) and power consumption. To overcome these problems and develop a next-generation, ultra-high sensitivity, flat image sensor, we have developed an FEA image sensor.
