摘要:
Methods and apparatus for temperature sensing in a detector system. Dark current from pixels in a pixel array of the detector system can be filtered to remove noise and processed to determine a temperature of the pixel array from the filtered dark current. Calibration of the dark current for a range of temperatures can be performed. In embodiments, the pixels comprise photodiodes.
