This thesis is concerned with the experimental determination of surface displacements of material foils by means of an automatic evaluation of the holographic interferograms obtained in testing. The experimental work utilizes a newly developed method referred to as the "holographic-electro-optical" technique that employs a specially designed microcomputer unit. The experimental procedure and the microcomputer organization are fully described. The application of this technique is illustrated by the evaluation of strain field and thickness changes at a large number of points on both sides of a commercial newsprint paper sample subjected to uniaxial loads. Furthermore, a new quantity called the "volumetric mass density" is introduced for this material for the first time that is experimentally evaluated and correlated to the obtained strain field. In the conclusion of this thesis general remarks concerning the holographic-electro-optical technique are given and the obtained results for the newsprint sample and future research are indicated.
