Abstract
A microbolometer imaging apparatus having an array of selectable substrate-isolated microbolometer detectors, a detector selection controller, and a readout circuit. The detectors may be exposed to a scene of interest, and each detector has a corresponding resistor value. The detector selection controller may selectively couple an electrical bias source to each detector. The readout circuit may establish an output signal representative of the resistance value of each detector. The readout circuit includes a feedback bias control circuit modulates the electrical bias source as a function of the output signal.
