ABSTRACT:
The invention relates to a method of measuring the eccentricity of a waveguide embedded in a cylindrical connector pin. The optical center of the end face of the waveguide is introduced into the mechanical axis of rotation of a distance sensor scanning the outer surface of the connector pin. Subsequently, the eccentricity of the waveguide is determined from the measuring values obtained during the relative rotation of the distance sensor along the outer surface of the connector pin.
