Abstract:

A radiation sensitive detector employed with a thermal radiation scanning system to receive images that are scanned across said detector at predetermined velocities. The detector is sensitive to these scanned images and generates minority photocarriers that drift along the length of the detector in the opposite direction as a majority carrier flow caused by an applied biasing field. The cross-section of the detector is non-uniform along its length direction so that the density and velocity of the photocarrier packets may be appropriately controlled over the length of the detector.
