In this paper we investigate the interaction of a bounded acoustic beam incident on a 90° wedge shaped sample immersed in a fluid (water). The variations of the amplitude of the signal radiated by the tip of the wedge in a plane perpendicular to the edge are recorded against the scattering angle and plotted in polar diagrams. The influence of different parameters such as the frequency and the angle of incidence on the experimental results are more specifically investigated. Some of the data are compared to optical experiments using a pulsed schlieren technique.
