Abstract: This work, aimed at quantifying the morphological variations induced by laser cleaning on stone materials, represents a very first attempt for a now quantitative means to reveal changes in stone surfaces. It is a, three-dimensional survey carried out by means of laser micro-profilometry and completed by statistical data processing. The acquisition and successive computation is performed on small selected areas both before and after the cleaning process.
