Study Of Fractal Objects By Means Of Low Angle Light Scattering

Low angle elastic light scattering techniques have been successfully applied to the study of solid particle size distributions. In this work we evaluate the possibility of extending this method to the study of fractal objects, like aggregating colloids. We present computer simulations on a peculiar iterative inversion scheme to recover the cluster gyration radiuses distribution. The computer simulations are made assuming realistic estimates of the noise associated to the measurements and the results of the data inversion procedure will be compared with the input data. The rate of convergence with the number of iterations will also be discussed.
