In the case of monodisperse dilute systems it is possible to calculate the distance distribution function for homogeneous and inhomogeneous particles of arbitrary shape. The distance distribution function enables one to find a rough classification of the shape and to determine the size of the particle. This function can be deconvoluted to the radial polarization density profile for particles with spherical symmetry. A number, mass or intensity distribution can be calculated from the light scattering data from polydisperse systems if the distribution can be described by a single parameter and if it is possible to calculate the shape factor of the particles, as it is the case for spheres and spheroids. The range of applicability of the method depends on the experimental set‐up, but is in most cases in the size range from 100 nm to several micrometers.
