Abstract
This paper analyzes the usage of the Yamaguchi's method, so-called the speckle pattern decorrelation, for determination of small static and dynamic object translations. At first the philosophy of the method is presented briefly. Then relationships between the cross correlation function and the small deformation tensor for the case of optically free space and image field are mentioned. Next, different experimental arrangements for the measurement of in-plane and normal object translations are analyzed. Possible measurement ranges and sensitivities for each arrangement are discussed, too. Finally, some results of our experiments are shown.
