One of the strategic goals of NASA's Planetary Science Mission is to advance scientific knowledge of the origin and history of the solar system, the potential for life elsewhere. The current STTR addresses this strategic goal. The proto-type AOTF-based SWIR spectropolarimetric imaging system developed in Phase I (which will be further optimized and integrated with optimal algorithm/software in Phase II), will be a useful tool in determination of chemical composition and physical characteristics of planets of interest, short period comets, primitive meteorites and asteroid bodies, and in identifying the sources of simple chemicals important to prebiotic evolution and the emergence of life. The concept and proto-type instrument developed in this program operates as a hyper-spectral imager as well as a spectropolarimeter. It is capable of obtaining hyperspectral images and the polarization state at the pixel level. It is compact, rugged in nature, fully electronically controlled and has no moving parts. The images can be taken at any desired wavelength/s within the operational range, in any sequence. Hyperspectral data cubes will be collected using aforementioned systems. Before processing the spectral information in the data, system non-uniformity correction, spectral response correction, and atmospheric correction will be applied to the data.
