Abstract
A photoconductive detector array which is responsive to infrared light to provide an electrical output response includes a substrate which is transparent to infrared light. A continuous layer of photoconductive material is disposed upon the substrate, and a conductive grid disposed on the continuous layer of photoconductive material divides the photoconductive material electrically but not physically into plural detector areas. Electrical connection structure is provided for individual electrical contact with a central region of each one of the plural detector areas. A method of making a detector array according to the invention includes forming plural perforations through the continuous layer of photoconductive material to expose the substrate. The electrical connection structure includes contacts which are secured to the substrate through the photoconductive material and which effect electrical connection with this material for each one of the plural detector areas.
