Paper Abstract

The Aerospace Corporation has conducted 5 flight series on the Kuiper Airborne Observatory (KAO) utilizing two-dimensional array infrared cameras. The KAO is operated by NASA Ames Research Center. These flights have several objectives with the primary task being the test in an aircraft environment of state-of-the-art two-dimensional arrays of both blocked impurity band and bulk silicon devices provided by Rockwell International and the Aerojet ElectroSystems Company under contract to the U.S. Army. There is extremely low crosstalk due to the SWIFET (switched FET) readout scheme employed on all three arrays flown to date. The - 500-element arrays were operated with a frame time of 307 psec which placed a large burden on the data recording equipment. The flight data were recorded on 8" floppy disks, a 9-track tape recorder, and a high-speed 28-track flight recorder. System sensitivities have been shown to be good enough to detect astronomical sources, both pointlike and extended in nature. Both staring and scanning experiments were performed using several astronomical sources. In the scanning experiments, a star was used as a point source which was scanned across the array at a fixed angle and angular rate using the rocking secondary mirror of the KAO. The data were then processed in a Time Delay and Integrate mode by the Boeing Aircraft Corporation; this TDI simulation achieved close to the theoretically predicted improvement in signal-to-noise ratio.
