Abstract
The statistics of partially developed speckle patterns produced by ref lection under coherent illumination can be used to determine the scatt ering properties of a mirror. The theory of the approach is presented, showing that in proper conditions the standard deviation of the speck le-field distribution expresses the finish grade of the reflecting sur face. Interferometric measurements are described, and experiments on s elected samples are reported.
