Abstract [en]

In recent years, TV holography is extensively implemented for determination of deformation and surface shape of diffusely reflecting surfaces. Such investigations are of primary importance in many applications, because these physical parameters are related to the functionality, integrity and performance of the engineering objects. In this paper, a new approach for determination of deformation and surface shape using simple optical configurations is presented. Description of each configuration, theory of fringe formation and the measuring sensitivity are discussed. Experimental results using four frame phase shifting technique are illustrated.
