Light-scattering measurements of micro-deformations in granular materials

Axelle Amon
Jérôme Crassous

Résumé

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.
