The Eos era will provide the Earth System Science remote sensing community with a wealth of new information on the interactions between the atmosphere, land surface, and oceans. High spectral and spatial resolution images provided by instruments such as the High Resolution Imaging Spectrometer (HIRIS) on the Eos-1 platform will be a key component of the Eos data set. We anticipate that the improved understanding of the Earth provided by Eos will create the need for even greater flexibility and measurement capabilities than represented by the current generation of sensors. The spectral flexibility, polarization selecting properties, and simplicity of acousto-optic filters (AOTF's) suggest an important application of these devices to future imaging spectrometers. AOTF's are compact, robust, solid-state crystals which provide rapid (millisecond), electronically-controlled spectral tunability in both states of polarization. In this paper, we will discuss concepts for spaceborne AOTF-based imaging spectrometers.
