Abstract

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