Abstract

An imaging spectrometer concept called digital array scanned interferometry (DASI) is being explored in our laboratories for terrestrial remote sensing applications. The essence of DASI operation is that interferograms are resolved spatially over one coordinate at the detector plane, and spatial information is obtained over the orthogonal coordinate. In this paper we focus on recent developments for approaching the fundamental capabilities of the DASI's performance, specifically the signal-to-noise ratio. We also describe selected land observations acquired from an airborne DASI operating in the 4550-9090 cm^-1 (1.1-2.2 micrometers ) spectral region with a spectral resolution of 266 cm^-1.
