  • Split dynamic range using dual array sensor chip assembly
    Patent number: 5101108
    Abstract: An infrared sensing array having a detector array, a readout circuit, and processing circuitry. The detector array includes first and second subarrays having different sensitivities associated therewith for detecting different brightness level ranges. The sensitivities of the subarrays are determined by sensing circuit elements in the readout circuit. As a result of the subarrays of different sensitivities, the composite dynamic range covered by the array is greater than the individually dynamic ranges of the subarrays.
