The applications of laser technology in the field of Rock Mechanics are at a stage of development that allow a reliable use for the reliefs of the mesostructure and for the morphological reconstruction of monuments in place of traditional techniques such as, for example, photogrammetry. The most recent research suggests that the laser may also allow assessment of characteristics such as roughness, which is known to affect the shear strength of discontinuities. Assessing the ratio between the energy of the reflected ray and the one emitted by the instrument, called "reflectivity (I)", it seems possible, also get information on the status of surface discontinuities or areas of historic monuments. This note presents results of research about relationship between the index (I) and the hammer Schmidt rebound r both on stone surfaces and on historical artifacts characterized by different levels of alteration.
