Abstract: The statistics of partially developed speckle patterns produced by reflection under coherent illumination can be used to determine the scattering properties of a mirror. The theory of the approach is presented, showing that in proper conditions the standard deviation of the speckle-field distribution expresses the finish grade of the reflecting surface. Interferometric measurements are described, and experiments on selected samples are reported.
