Paper Abstract

A simple experimental test bench is described for the measurement of eccentricity of fiber optic connectors for telecommunications applications. The measuring principle is based on the detection of the track of the light beam exiting from the fiber optic tip by means of a 2D position sensing detector. Displacement due to fiber eccentricity, which is in the order of a few micrometers can be optically amplified by lenses in order to improve eccentricity measurement uncertainty. Optomechanical and electrical solutions which have been used in order to reduce the global measurement uncertainty and the effect of many interfering quantities has been deeply studied form both a theoretical and experimental point of view. Finally some operating consideration is also discussed.
