Operation and calibration of self-integrating multiplexed arrays (Contributed)
Abstract
Multiplexed infrared detector arrays that use a direct, self-integrating input SFD (Source Follower per Detector) circuit have become available to the astronomy community. Because of its simplicity and flexibility, this circuit is used in several array designs, including the 58-by-62 element arrays offered commercially by Santa Barbara Research Center. The SFD circuit has been successfully coupled to both photovoltaic and photoconductive detectors. This paper discusses the theory of operation of the SFD input and demonstrates that a calibrated two-dimensional image can be attained with a dark slide and a single flat-field source.
