Abstract : The purpose of this program is to provide an 'in-house' government capability for measuring and characterizing the performance of infrared sensors operating under low-background conditions. Instrumentation is being developed to allow detector measurements at background flux levels from 1,000,000 to 10 to the 16th power photons/sec/sq cm, over the spectral range from 1 to 20 microns. The detector parameters to be measured and characterized are spectral response, responsivity, noise spectrum, frequence response, detector resistance, and detector impedance. These parameters will be measured and correlated as a function of background flux level, signal irradiance, and detector bias. Possible additional parameters which prove to be useful in describing the performance of a detector will, of course, be measured. (Author)
