Title: Micro LIBS Scan Elemental Mapping: a powerful tool for Cultural Heritage studies.

ICCOM Principal Investigator: Stefano Legnaioli.

Project type: International.

Duration: 01/2019-12/2022.

Abstract: To characterize Cultural Heritage artifacts, Laser Induced Breakdown Spectroscopy (LIBS) offers interesting advantages with respect to other methodology as its simplicity of realization, the ability to make instantaneous measurements without sample pre-treatment and the low cost. Furthermore, using the laser as a drill, LIBS allows to realize depth analyses. The main goal of the project is the optimization of a micro-libs scanning tool for the materials mapping with the development of a compact, transportable, economic device, able to analyze materials with a strong intrinsic inhomogeneity or for the analysis of stratified materials. For this purpose, different types of lasers and spectrometers will be tested to improve the S/N ratio of the acquired spectra. The data obtained will be processed through a series of Matlab scripts, useful to analyze a huge amount of data. We will make extensive use of techniques and algorithms typical of the field of multispectral analysis and neural networks.
