  • Non-delineated semiconductor detector array for infra-red
    Patent number: 4531059
    Abstract: A detector comprising an elongated strip of semiconductor material which is photoconductive by the generation of electron and hole photocarriers when an image is moved along the strip. The strip includes an active region and a readout region. A first bias current is applied through the active region of the strip thereby producing an ambipolar drift of photocarriers in the strip whose velocity substantially matches the velocity of the movement of the image along said strip. A second bias current is applied to the readout region of the strip so that the drift of the photocarriers in the readout region has a velocity which is greater than the velocity of the drift of the photocarriers in the active region of the strip, thereby decreasing the time for readout.
