Abstract : Conventional three-phase, single-level CCD technology has been utilized to multiplex the signals from teen elements of a 0.1 eV HgCdTe photoconductive array to produce a single serial video output without degradation in the detectors' signal-to-noise ratios, detectivity, or channel-to-channel isolation (crosstalk). Interface circuitries between the detector elements and the CCD inputs were fabricated using monolithic bipolar ICs which had been custom designed at Texas Instruments prior to this contract for use in TI's modular FLIR systems. The clocking rates were selected to simulate first-level operation of a two-level multiplexer system operating with a 360-line parallel-scan format with 2:1 interlace (i.e., 180 elements). (Author)
