Two-dimensional light-scattering patterns from aggregates have undergone feature extraction followed by multivariate statistical analysis. The aggregates are comprised of primary particles of varying shape and size. Morphological descriptors (features) were extracted by a nonlinear filtering algorithm (spectrum enhancement) and then processed by principal component analysis and discriminant function analysis. The analysis was performed on two data sets, one in which the aggregates had a fixed primary particle size but varied in overall dimension and another in which the aggregate size was fixed but the primary particle size varied. Classification of the samples was performed adequately, providing some distinction among the limited classes that were analyzed.

  29. The near-backward direction was chosen for these experiments to enhance the morphological and material effects the aggregate had on the light scattering. The forward scattering is dominated by diffraction and does not offer as much useful information about particle morphology and material properties as the backward-scattering direction.
  30. The laboratory reference frame differs from the traditional scattering reference frame in that the illuminating laser is directed along the x axis, and the z axis points up. Traditionally the laser source propagates along the z axis with the x axis directed up. The conventional geometry is typically chosen to simplify scattering calculations. A more detailed description of the laboratory reference frame is given in Ref. 4, which also includes a transformation between the two geometries.
