Reconstruction of potential from dynamic experiments.
In experimental studies of a surface by an underdamped mechanical surface force probe the "tip" can return repeatedly to the same points in space. This causes a problem in using the experimental data to extract information about the surface structure. We propose an approach which allows one to extract the mesoscopic surface structure from dynamic experiments with underdamped systems. The approach was tested on numerically generated random fractal potentials and is applied to extract potential relief from real experimental data.
