The sizing of fibres using optical scattering

D J Somerford, S R Powers

    IARC Scientific Publications
    |January 1, 1980
    PubMed
    Summary

    Fraunhofer diffraction accurately models light scattering from absorbing cylinders down to 4 micrometers. A Fourier transform inversion method determines fibre width size distribution without initial calibration.
