Abstract
A high-speed gamma pulse suppression circuit employing a frequency discrimination and sampling technique for elimination of gamma induced noise from semiconductor infrared detectors. The gamma pulse suppression circuit includes a high pass filter for separating high-frequency gamma induced pulses from a detector signal and a gamma pulse detector for detecting the gamma induced pulses. The gamma pulse suppression circuit is connected in parallel with a detector readout circuit such that the suppression circuit causes the readout circuit to discard samples of the detector signal in which gamma induced pulses are detected. The gamma pulse suppression circuit provides effective and efficient real time gamma pulse suppression by completely eliminating the detected gamma pulses from the detector signal, while preserving the quality of the signal.
