Application of light scattering from dielectric cylinder based upon Mie and Rayleigh-Gans-Born theories to polymer systems. I. Scattering from a glass fiber.

Abstract

Light scattering from a glass fiber was investigated for a rigorous evaluation of its size and refractive index. Angular variation of forward scattering intensity from the fiber of about 5 μm in radius with or without immersion liquid was quantitatively measured by a laser photometric apparatus. The results were analyzed by Mie and Rayleigh—Gans—Born (R.G.B.) scattering from an isolated and infinitely long cylinder. Discussions were made on criterion of R.G.B. scattering, when the theory is applied to the system, and on approximated but rapid and convenient methods in evaluating the size and refractive index of the fiber. © 1978, The Society of Polymer Science, Japan.
