Probability Distribution of Multiple Scattered Light Measured in Total Transmission

Abstract

We report the first measurement of the distrubution function of the fluctuations on the total transmission of multiple scattered light. The shape of the distribution is predominantly Gaussian. A non-Gaussian contribution to the distribution function is found, caused by correlation in the cubed intensity. The scattering diagrams responsible for this new correlation are calculated without free parameters, and a good agreement is found between experiment and theory.
