Acousto-optical measurement inside transparent media is a well known non invasive method for acoustic fields probing. The optical index variations induced by acoustic wave propagation in a liquid or transparent solid can be detected using several techniques: optical deflection, diffraction methods, etc ... Last year, X. Jia, G. Quentin and Laszlo Adler [1] described the ability of a interferometric detection technique to provide local and quantitative measurements of pressure fields in water as well as dilatational fields inside transparent solids. This method combines the acousto-optical effect with heterodyne interferometry. It measures the phase shift of a laser beam passing through an ultrasonic wave. The interferometric detection provi...
