A method, believed novel, is demonstrated for determining the strain-optic coefficient profile as well as the residual–stress profile of an optical fiber by use of a modified polariscope combined with a fiberelongation apparatus. Measurement results of the residual–stress and the strain-optic coefficient profiles for Ge–doped and Er–Ge–Al–doped optical fibers are demonstrated with this method.
