Time-resolved spectral imaging of LIBS plasma at low pressures for the exploration of Solar System bodies

Abstract

Laser-induced breakdown spectroscopy (LIBS) is an increasingly important technique for the robotic exploration of Solar System bodies. We investigate the spatial distribution of species inside the plasma plume of a LIBS measurement for different atmospheric compositions and pressures. The results can help with the interpretation of Martian LIBS data (ChemCam, SuperCam) and from other planetary exploration missions using LIBS.
