With the progress of the smoothing technique of sliding surfaces, lubrication technology at small sliding gaps is required. However, the lubrication phenomenon at small sliding gaps has not been fully clarified due to the difficulty of measurement. For clarifying the lubrication phenomena, the relationship between the sliding gap and forces that separate the sliding surfaces is needed. In this study, we aimed at proposal of a method for measuring the distribution of nanometer sliding gaps. We considered the method that can provide high lateral resolution and high thickness resolution for application to micro machines. We tried a new method that is based on ellipsometry and showed its feasibility.

随着滑动表面光滑化技术的发展，对滑动间隙小的润滑技术提出了更高的要求。然而，由于测量的困难，在小滑动间隙处的润滑现象尚未完全澄清。为了阐明润滑现象，需要滑动间隙和分离滑动表面的力之间的关系。在本研究中，我们的目的是提出一种测量纳米滑动间隙分布的方法。我们考虑的方法，可以提供高的横向分辨率和高的厚度分辨率的应用于微机械。我们尝试了一种新的方法，这是基于椭圆偏振，并证明其可行性。
