Calibration of the HI STAR Sensors.

Abstract

Problems exist in calibrating a cryogenically cooled infrared sensor system in the laboratory. Although there are limited laboratory facilities which attempt to simulate the actual operational environment, the sensor-tester interface has created difficulties for calibrating LWIR sensors in general. The procedures used to calibrate the AFGL infrared celestial survey experiments are described in detail. It was found that 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. (Author)
