Paper Abstract

The paper deals with the theory of measurement of an object in-plane velocity (object as a rigid body) by means of the method availing the statistical properties of the speckle field (speckle pattern). At first, the general theory of determination of the small deformation tensor of an elementary area of an object surface using the electronic speckle correlation in the optically free space and in the image field is briefly mentioned. Furthermore, the philosophy of measurement and interpretation of measurement is presented and the analysis of sensitivity and accuracy is also shortly done.
