Whereas correlation spectroscopy gives reliable information on the size of immersed particles in those cases where the size distribution is narrow, large problems arise for more complex particle distributions. For instance, samples containing distinctly different particles of rather similar size lead to correlation functions which are very close to those of monodisperse samples. We present a measurement technique which is based on angle dependent measurements of 3D cross correlation functions and an evaluation scheme which uses the results of the Mie theory. The experimental technique warrants applications to strongly scattering samples. Having tested this procedure with mixtures containing standard latex particles we applied it to a sample of skimmed, homogenized milk.
