A technique for measuring the lateral and axial displacements of the focal point of an acoustic focused beam reflected at a water-aluminum interface in the neighborhood of the Rayleigh angle incidence is presented together with a qualitative representation of other nonspecular phenomena, based on the cartography of the reflected beam. A study of the feasibility of the experiment and the choice of the transducer is carried out. The results obtained are in agreement with theoretical predictions.
