Abstract
A two dimensional focal plane array of Schottky photodiodes on a silicon substrate for infrared imaging. The array is designed for mating with multiplexing circuitry and has a self-guarding feature wherein adjacent Schottky electrodes act as guard electrodes. This feature allows a substantial increase of the focal plane area coverage ratio.
