Paper Abstract
This paper describes a noncontact fiber optic probe for measuring tangential velocity of a surface and its normal displacement. The developed sensor is based on the intensity modulation of back-scattered light achieved by interaction of collimated laser beams with the moving surface; the probe has been realized using optical fibers and micro-lenses in order to miniaturize the system. Both the measurements of velocity and displacement are simultaneously obtained by using cross-correlation techniques. The device is tested on a specially prepared belt drive and its performance is compared with two different commercial measurement systems.
