Paper Abstract

This paper proposes a full-field and simultaneous method to visualize acoustic waves at the surface of granular media, using a three color digital holographic set-up. Experimental results permit the quantification of the response of the medium to an acoustic excitation, and exhibit propagative longitudinal waves, as well as transverse waves. This new approach also permits the measurement of the influence of a small buried obstacle.
