Abstract

Systems and methods for imaging in short-wave infrared (SWIR), photodetectors with low dark current and associated circuitry for reducing dark current, and methods for generating image information based on data from a photodetector array. A SWIR imaging system may include a pulsed illumination source operable to emit a plurality of pulses of radiation in the SWIR band toward a target, causing radiation to be reflected from the target; (b) an imaging a receiver comprising a plurality of germanium PDs operable to detect said reflected SWIR radiation; and a controller operable to control activation of said receivers for an integration time during which said detected The accumulated dark current noise does not exceed the read noise for the time-independent time.
