Abstract
Systems, methods and sensors detect changes in incident optical radiation. Voltage is applied across one or more active areas of a detector while the incident optical radiation illuminates the active areas. Current is sensed across one or more of the active areas, a change in the current being indicative of the changes in incident optical radiation.
