【 摘 要 】

We present a hybrid acoustic imaging system to directly visualize acoustic waves propagating within a single anisotropic crystalline plate. A high frequency acoustic point focus lens was used to form a small point source within the 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.
