Abstract

A four-point joint density function for the intensities of a fully developed speckle pattern is derived as an infinite summation of products of modified Bessel functions of the first kind. It is found that the special cases of this density function will agree with all the previously known results. With interest growing rapidly in the higher-order correlations of signals, this result will be useful in general optical scattering problems.
