We present a hybrid acoustic imaging system to directly visualize acoustic waves propagating within a single anisotropic crystalline plate. An acoustic lens (point focus, continuous wave, frequency; 180MHz) was used to form a point source (diameter of point: approximately 5m) within the silicon plate. A laser interferometric system was used to visualize the acoustic wave propagation. Distinct amplitude patterns at each focal plane were experimentally visualized. The patterns are also theoretically calculated with an Angular Spectrum of Plane Waves method.
