Monolithic InSb imaging arrays with charge-coupled device /CCD/ readout

The paper demonstrates the detection of infrared radiation and signal readout on a monolithic InSb charge coupled infrared imaging device. The device is a 20-element linear imager with MOS detectors coupled to a four-phase, surface-channel, charge transfer structure. The charge transfer device is p-channel and has planar ion implanted diode structures for zero input and charge readout. Sensitivity measurements on the MOS infrared detectors were determined for the 20-element array. Data are presented on the operational characteristics of the 20-element linear imager under various conditions of electrical and optical inputs in both multiplexed and a time delay and integration (TDI) mode. Plans are discussed for a monolithic InSb 100-element linear imager and a 20 x 16 TDI linear imager.
