Adaptive adjustment of the operating bias of an imaging system

摘要: An imaging system includes a shutter, an array of photodetectors, and electronic circuitry associated with the photodetectors to read intensity values from including elements configured provide operating bias point photodetectors. The components, such as controller, adaptively adjust for wherein adjustment is based at least in part on intermittent measurement flat field image. During use, can be perform adjustments changes photodetector intermittently acquired images. Adjustment may compensation drift over time and/or electronics due effects but not limited temperature changes.
