Measurement of optical fiber diameter using the fast Fourier transform.
The variation of the fringe spacing of the far zone scattered intensity of an illuminated optical fiber has been plotted vs the scattering angle, theoretically and experimentally. A method for measuring fiber diameters by taking the Fourier transform of the scattering intensity is described. Theoretical and experimental resultshave been compared at various angles for different fiber diameters.
