We present a new full-field strain measurement method based on diffusing-wave spectroscopy. Our technique makes it possible to measure strains in the vicinity of the surface of highly light-scattering materials. Its main feature is an extreme sensiti

It is well known that the transient behavior during drainage or imbibition in multiphase flow in porous media strongly depends on the history and initial condition of the system. However, when the steady-state regime is reached and both drainage and

International audience; We have studied the effect of an external acoustic wave on bubble displacements inside an aqueous foam. The signature of the acoustic-induced bubble displacements is found using a multiple light scattering technique, and occur

International audience; 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.

International audience; We propose an experimental setup based on diffusive wave spectroscopy for studying deformations of a solid material. The scattered waves are measured during the deformation of the solid material at different locations of its s
