Real contact area between a rough rubber hemisphere and a glass plate under dry conditions was visualized by white light interferometry. The contacting state of the real contact area in the starting process of relative motion was analyzed using the interference intensity. The results obtained are as follows: (1) The real contact area was measured by fitting of the normal distribution for the intensity histogram of interference images. The experimental values for a smooth lens specimen agreed with the theoretical values under the Hertzian contact. (2) In the starting process of relative motion, the real contact areas decreased with increase of the tangential load and became approximately constant by initiating of the macroscopic sliding. (3) PIV analysis that assumed a real contact points as tracers was performed and visualized the distribution of stick/slip region at the real contact area.
