Abstract
Abstract A far-IR imaging array comprising a two-dimensional array of chalcogenide glass thermistor bolometers. A two-dimensional system of metallic strips arranged in a grid structure has insulating film between the strips at the points of intersection of each horizontal and vertical strip. A bolometer is placed at each intersection so as to bridge the insulator thereat. If an infrared image is focused on the array, the resistance of each bolometer can be determined by a scanning system.
