ABSTRACT:
Parameters of a clad optical fiber are measured by irradiating the fiber with a laser beam to generate a scattering pattern. Measurements are made of fringes and modulations in the scattering pattern and these measurements are translated into such parameters as the diameter of the core and cladding thickness as well as the deviation from concentricity of the core of the clad optical fiber.
