Abstract :
A scanning probe microscopy (SPM) for visualization of standing acoustic waves in piezoresonators based on registration at every pixel the wave inherent electric field (normal to surface) is developed. The physical background of the presented method is electric charge induction in a probe by wave electric field. As in any scanning probe microscopy, the probe is the key part and the resolution is the goal. For the case, the long-range nature of electric field rise the main hindrance. In the paper, a complete analysis of basic/fundamental requirements and interdependences of the method are presented together with analysis of probe functioning focused on effective aperture. An SPM system, builded in accordance with presented analysis, is described and images of standing waves of different modes are presented.
