Abstract

Two polarization configurations for the light scattered from a mixture of small particles are used to estimate the fraction of spherical particles it contains. The mixture is composed of 0.3-μm alumina polishing powder and 0.106-μm polystyrene spheres. The alumina is an ensemble of randomly oriented irregularly shaped particles. The fraction of spheres in the scattering volume is varied and compared with that deduced from the optical information.
