Abstract

A new method is proposed for evaluating the local displacement of objects in speckle photography by using a Wigner distribution function (WDF). It is applied to evaluate the displacement of 1D specklegrams as well as specklegrams of the ground glass and rubber plate which are slightly shifted and stretched, respectively. As a preliminary study, the local spectra W(x,(omega) ) are qualitatively and quantitatively verified in comparison with the theoretical results and the conventional Young''s interference fringes. The results show the feasibility of evaluating the displacement of objects using the WDF.
