Abstract
Polarized light scattering from systems having random assembly of anisotropic fibrils with finite length L and infinitely thin thickness were theoretically calculated. The calculations were carried out for the fibrils randomly oriented in three-dimensional space. As for orientation of optic axes within the fibrils, two types of fibrils were considered; one in which the orientation of the optic axes is fixed in a plane within the fibril and the other in which the orientation is cylindrically symmetric around the fibril axis. Differences in the scattering patterns from two types of the fibrils were discussed. By comparing the scatterings from two types of the fibrils with experimental scattering patterns, it is suggested that the fibrils which show maximum HV scattering intensities at azimuthal angles μ=0° and 90° must be the former type of the fibrils. However for the fibrils which show maximum HV scattering intensity at μ=45°, a unique determination of the types of the fibrils seems to be difficult by light-scattering method alone.
