Abstract

A fiber optic surface sensor is described in which depolarization of light by a rough surface is measured. Polarization maintaining single mode fibers are used for the illumination and observation of the reflected light. An optimization of the measurement configuration aimed in restriction of the observation to the first Fresnel zone has been performed.
