On-line Topography measurment of lubricated sliding contacts

We have developed an instrument that is able to obtain topographic data on different scale during the sliding experiments. It consists of a friction force sensor, a digital holographic microscope, a radionuclide technique (RNT) measurement system and an atomic force microscope . More details about this tribometer can be found in  S. Korres and M. Dienwiebel, Rev. Sci. Instrum. 81, 63904 (2010)
