Abstract

This paper deals with a determination of so called small deformation tensor of the elementary area of an object surface by means of an optical experimental method, availing of statistical properties of the speckle field in an optically free space geometry. The small deformation tensor and a correlation function are briefly mentioned, and the main emphasis is aimed at the theoretical derivation of the relationship between the correlation function of two speckle intensities, being recorded before and after deformation. This results in the relationship theoretically enabling a determination of all components of a small deformation tensor by means of a relatively simple optical arrangement in connection with computer and linear CCD detector.
