Due to the unique perspective of thermal infrared spectral measurements of geologic targets taken obliquely from a planetary rover or fixed lander, we have conducted several series of experiments designed to explore the various interferences which may arise from the local environment. Additional information is contained in the original extended abstract.
In this paper, we explore the use of remote LIBS combined with pulsed-laser Raman spectroscopy for mineral analysis at a distance of 10 meters. Samples analyzed include: carbonates (both biogenic and abiogenic), silicates, and sulfates. Additional information is contained in the original extended abstract.
Raman spectroscopy is typically envisioned as an in situ analysis technique. Raman spectra measured remotely (10s of meters) from a planetary lander can be calibrated to spectral radiance and the Raman scattering efficiency can be determined.
We have examined effects of grain size and grain orientation on the Raman spectra of quartz and olivine to evaluate the effect of these parameters on in situ and remote analysis of planetary surface rocks.
