Observations and Calculations of Light Scattering from Clusters of Spheres

Abstract

Two-dimensional angular optical scattering (TAOS) from clusters of polystyrene latex spheres is measured in the near-forward and near-backward directions. In both cases, the scattering pattern contains a rich and complicated structure due to the interaction and interference of the light among the primary particles. Calculations are made for aggregates similar to those generated experimentally that demonstrate the rich structure in the scattering pattern. A comparison of the experimental and theoretical TAOS gives good qualitative agreement.
