Integrating LIBS LIF Raman into a single multi-spectroscopic mobile device for in situ Cultural Heritage analysis

摘要

Heritage science aims to study cultural heritage objects through the developing and studying conservation issues to advisenew restauration approach. In addition, the development of new tools is one of the major accesses, which allows to increaseknowledge in archaeology and to characterize the materials. This paper is focused on the development of a Laser-InducedBreakdown Spectroscopy-Laser-Induced Fluorescence-Raman Spectroscopy (LIBS-LIF-Raman) portable instrument forsupporting conservation campaigns when extensive measurements and on-site decision-making in cultural heritage. Sucha multi-analytical prototype instrument is able to combine these three laser-based spectroscopic techniques tosimultaneously provide complementary elemental and molecular information from the same analysis point. To that purpose,different laser sources, appropriate optics and detection modules have to be examined in order to integrate them on amobile platform.
