Raman Mapping of Mars Relevant Minerals using Multiple Excitation Wavelengths
Mentor: Rohit Bhartia (JPL)

We are currently developing Raman/fluorescence micro-mapping instrument that would enable an arm mounted flight instrument for future Mars Rovers. This micro-mapper will combine deep UV Raman & fluorescence spectroscopy to enable imaging of organics entrained within rocks, with Raman spectroscopy used for detailed mineralogy, enabling spatially correlated organic-mineral maps.

CURE student tasks: Properties of asteroids, planning, observations, and data analysis. As part of this effort, we are conducting a systematic comparison of Raman spectra for Martian-relevant minerals using multiple excitation wavelengths, including deep UV in order to determine the optimal combination of wavelengths and techniques required to acquire maps from potential samples.
