Diffusive Wave Spectroscopy is used to measure very small strains of the order of 10−5 − 10−3. That method gives a new full-field measurement of the strain at the vicinity of the surface of highly scattering materials. The principle of the method is presented and application to the measurement of micro-deformations in a granular material are shown.
