UV Raman spectroscopy—A technique for biological and mineralogical in situ planetary studies
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2007We report on the great advantages of using deep UV Raman system for in situ planetary applications. Among them are to be mentioned: (I) higher scattering efficiency compared to VIS-IR Raman excitation wavelengths, (II) electronic resonance effects which increase the intrinsically weak Raman signal thus improving the S/N ratio of the detected Raman ...

Mineralogical study of proto-planetary disks in FU Orionis stars
Proceedings of the International Astronomical Union, 2009AbstractWe report on mid-infrared (8–13 μm) spectroscopic observations of eight FU Orionis type objects and discuss a qualitative initial mineralogical analysis.

Optical design of a compact imaging spectrometer for planetary mineralogy
Optical Engineering, 2007We present the design of a compact, wide-angle pushbroom imaging spectrometer suitable for exploration of solar system bodies from low orbit. The spectrometer is based on a single detector array with a broadband response that covers the range 400 to 3000 nm and pro- vides a spectral sampling of 10 nm.

Abstract The importance of the discovery of jarosite at the Meridiani Planum region of Mars is discussed. Terrestrial studies demonstrate that jarosite requires a unique environment for its formation, crystallizing from highly acidic (pH 2 that reacted with aqueous solutions in shallow aquifers or on the martian surface. This interaction forms both

The Ultra-Compact Imaging Spectrometer (UCIS) is a miniature telescope and spectrometer system intended for mapping terrain mineralogy over distances from 1.5 m to infinity with spatial sampling of 1.35 mrad over a 30° field, and spectral sampling of 10 nm in the 600-2500 nm range.
