A 640 × 480 pixel field emitter array (FEA) image sensor with a high-gain avalanche rushing amorphous photoconductor (HARP) target was fabricated and tested as a step toward the development of ultrahigh-sensitivity compact image sensors for high-definition TV cameras. Experiments showed that the prototype sensor could obtain clear images with little noise under illumination on a level equivalent to moonlight, with sufficient resolution while consuming far less power than current ultrahigh-sensitivity pickup tubes. Furthermore, various technologies which were suitable for practical image sensor have been developed.
