Abstract

Problems exist in calibrating a cryogenically cooled infrared sensor system in the laboratory. Although there exists limited laboratory facilities which can simulate the actual operational environment, the sensor-tester interface has, in the past, created difficulties in calibrating LWIR sensors. The procedures used to calibrate the AFGL infrared celestial survey experiments are described in detail. It was found that the stars are reliable calibration sources which offer several advantages over laboratory references. The long term stability of the sensor systems as well as linearity of the system are discussed. Anomalous behavior in the parallel biased detectors was observed and is described. Suggestions are offered to improve calibration of future cryogenically cooled infrared celestial sensors.
