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

Heritage science aims to study cultural heritage objects through the developing and studying conservation issues to advise new restauration approach. In addition, the development of new tools is one of the major accesses, which allows to increase knowledge in archaeology and to characterize the materials. This paper is focused on the development of a Laser-Induced Breakdown Spectroscopy-Laser-Induced Fluorescence-Raman Spectroscopy (LIB S-LIF-Raman) portable instrument for supporting conservation campaigns when extensive measurements and on-site decision-making in cultural heritage. Such a multi-analytical prototype instrument is able to combine these three laser-based spectroscopic techniques to simultaneously 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 a mobile platform.
