Abstract : Analytical and numerical results describing the statistics of scattered signals observed interferometrically are presented. Observable quantities are given in terms of two wavefront parameters which are invariant in post-scattering propagation: the ratio of nonscattered to scattered flux and the wavefront autocorrelation. The analytical result refers to the average output of a phase-switch or coherently detecting phase-sweep interferometer. Numerical results are given for distributions and average characteristics of real amplitude-product and phase-difference, which are observable with phase-sweep interferometers employing other detection techniques. The treatment is based on the assumption of a randomly phased angular spectrum. However, no restrictions are placed on the degree of scatter or on the form of the autocorrelation function. (Author)
