Abstract

A 128-element InSb linear detector array read out with a field effect transistor (FET) multiplexing scheme has been developed at the Jet Propulsion Laboratory: State-of-the-art NEP, uniform response, on-detector charge integration, and very low focal plane heat load compared to that of discreet detector arrays allows this type of array to open new possi-bilities for spaceborne near-infrared imaging spectrometers. Large number of cooled detector elements are feasible with the new technology, making it practical to design sensitive spectrometers even for spinning spacecraft where simultaneous wavelength coverage is necessary to avoid confusion of spatial with spectral variations.
