The aim of this paper is to measure quantitatively the degree of spatial coherence across the beam of a multi-mode laser after propagation in a random medium and, by analyzing the obtained spatial coherence, to obtain information on the characteristic parameters of the random medium. A method has been proposed and experimentally used, which is based on ensemble-averaging, by means of an electric technique, over instantaneously fluctuating interference patterns produced by thedouble pinhole experiment.
