摘要

In this paper, a recently developed light-section technique is demonstrated as a viable technique for the measurement of the topography of moving surfaces. The sensitivity and precision of this technique are statically and dynamically evaluated for samples of different roughness. It is shown that an optical system using the light-section method is not only precise but also immune to the effects of perpendicular and lateral motion of the surface. It is therefore well suited to on-line monitoring of the change of profile of moving surfaces. The technique, with its ability to measure the topography of moving surfaces without contact, provides a most effective tool for the study of wear and lubrication mechanisms under partial elastohydrodynamic lubrication.
