Measurement of Size Distribution in Dense Particle Fields

  • A. A. Hamidi
  • J. Swithenbank


The problem of multiple scattering of light by dense particle fields in a light scattering measurement technique is resolved. A mathematical model for this phenomenon is developed which predicts the light energy distribution produced by any given size distribution at any obscuration. The mathematical analysis is carried out for Fraunhofer and the anomalous diffraction theories. A systematic procedure is established to correct for the effect of multiple scattering. Excellent agreement with experimental results is obtained. The study therefore enables the application of the measurement technique to very dense particle fields.
