Paper Abstract

The Airborne Visible/Infrared Imaging Spectrometer (AVIRIS) instrument uses four separate focal plane assemblies consisting of line array detectors that are multiplexed to a common J-FET preamp using a FET switch multiplexing (MUX) technique. A 32-element silicon line array covers the spectral range from 0.41 to 0.70 pm. Three additional 64-element indium antimonide (InSb) line arrays cover the spectral range from 0.68 to 2.45 pm. The spectral sampling interval per detector element is nominally 9.8 nm, giving a total of 224 spectral channels. All focal planes operate at liquid nitrogen temperature and are housed in separate dewars. Electrical performance characteristics include a read noise of < 1000 e- in all channels, response and dark nonuniformity of 5% peak to peak, and quantum efficiency of ) 60%.
