Abstract
The analysis of intensity and polarization fluctuations of light scattered by systems with particles is of interest in the resolution of the so-called inverse problem. In this chapter we study the possibility of obtaining information, by means of light scattering techniques, about the geometrical and optical properties of systems composed of two Rayleigh particles, either in volume or located on a substrate. Intensity fluctuations are studied using the normalized second order moment. Polarization fluctuations are studied using the probability of getting null values when measuring the cross-polarized component P(I cross =0). It is observed that the behavior of these parameters depends on both the polarizability of the particles and the distance between them. Some experimental results are shown with measurements of the parameter P(I cross =0) for the case of metallic particles on a flat conducting substrate.
