Correlation analysis of speckle pattern of inhomogeneous microrelief

We have derived that the resulting speckle pattern has the highest possible contrast. The produced analytical estimation of the speckle pattern distribution description is reached at the assumption of the rectangular distributions of the used parameters. The purpose of the given work is to develop a technique of the detection of heterogeneity in a structure of the surface microrelief, using an analysis of a speckle pattern formed by this surface.
