Optical fiber coating concentricity: measurement and analysis.
Backscattering of laser light that is incident at right angles to the axis of an optical fiber is utilized to evaluate the degree of eccentricity of a plastic jacket on the fiber. An analytical treatment of the problem based on ray optics is shown to be in excellent agreement with experiments, which are capable of detecting coreto- jacket offsets on the order of 1 microm.
