Paper Abstract

An optical method for measurement of static deformations is presented. This non-contact technique is based on interference of the light and the principle of phase shifting. The theory of phase shifting interferometry is shortly described and there are given four possible multistep algorithms for evaluation of the phase difference of the interference field induced by a static deformation. It is shown a new way how to evaluate the phase difference of the interference wave field, which is closely related to deformations of tested objects. The main part of this paper deals with an analysis of proposed algorithms. The experimental system, which is applied in static deformation measurement and which can be easy modified for industrial applications, is described and the method is demonstrated on an example.
