Integrating 128-element linear imager for the 1 to 5 microns region
Useful charge integration has been achieved in high quality photovoltaic InSb diodes when combined with a FET multiplexing (MUX) scheme. An experimental detector assembly with a linear array of 128 InSb diodes coupled to a FEX MUX has been developed. The first stage J-FET preamp, pixel reset switch, MUX, and the InSb array are contained in a hybrid microcircuit of compact dimensions. A low noise preamplifier topology which capitalizes on the low video line capacitance inherent with hybrid fabrication techniques is also utilized. Measurements indicate a signal-to-noise ratio of over 1000:1 and response uniformity of + or - 2 percent. Sample images show subtle detail which supports the estimated radiometric sensitivity of 0.01 K.
