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.
在利用欠阻尼机械表面力探针研究表面的实验中,“探针尖端”能够反复回到空间中的相同点。这在利用实验数据提取有关表面结构的信息时会产生问题。我们提出了一种方法,该方法能够从欠阻尼系统的动态实验中提取介观表面结构。该方法在数值生成的随机分形势上进行了测试,并应用于从实际实验数据中提取势起伏。
