  • Method and apparatus for measuring eccentricity in a optical fiber
    Patent number: 6937325
    Abstract: A method and an apparatus for obtaining measurements of eccentricity in optical fibers, from which the spin imparted to the optical fiber can be ascertained. The method and apparatus enable eccentricity to be measured in such a way that this measurement can be utilized to determine the amount of spin imparted to an optical fiber as the optical fiber was being drawn, although the eccentricity measurement may be used for purposes other than to determine the amount of spin in the fiber. By viewing the fiber from one or more positions along the length of the fiber, the eccentricity of the fiber as a function of position along the length of the fiber can be determined. The amount of spin in the fiber can then be determined from the eccentricity measurement.

In accordance with the present invention, it has been determined that by viewing the fiber from one or more positions along the length of the fiber, the eccentricity of the fiber as a function of position along the length of the fiber can be determined. The amount of spin in the fiber can then be determined from the eccentricity measurement.
