Paper Abstract

A dynamic speckle-interferometry method based on continuous monitoring of speckle-fields reflected from two objects under deformation is described. The aim of the paper is to verify the correctness of the formula relating the vector of relative displacement of body areas to the order of interference at the observation point. The formula coincides with a similar formula found in holographic interferometry. The lines of interference periods found on the image by dynamic interferometry are shown to agree well with the lines of equal interference periods obtained under identical conditions by holographic and correlation interferometry.
