Infrared Detector Array Test Program for the Kuiper Infrared Technology Experiment (KITE)
Abstract
Three two-dimensional infrared arrays have been tested under flight conditions on the NASA-Ames Research Center Kuiper Airborne observatory (KAO). Two series of 3 flights each were undertaken. Two of the arrays were manufactured by Aerojet ElectroSystems Company; these were a 16 x 32 pixel Si:Bi bulk array and a 16 x 32 pixel Si:As MC2 (impurity band conduction) array. The third array, a BIBIB (black-illuminated blocked impurity band) Si:As detector, with 10 x 50 pixels, was manufactured by Rockwell International. This report concentrates on several aspects of general array performance observed during the sixth flight, during which each of the arrays was mounted on the telescope. Each array was exposed to background radiation from the telescope and the atmosphere and each was able to detect a star. The performance characteristics of representative array pixels are presented in some detail, while tables show the performance of all pixels as a set. Anomalies and other unusual characteristics of the data are discussed, linking each characteristic to its apparent source in the arrays themselves, the associated multiplexers, or other elements of the array electronics system. The techniques and nature of the flat fielding required and correction for local background are also addressed. Properties of the noise and the uniformity of the arrays are examined in detail with tables and gray-scale plots.
