Abstract

Within this report the practical uses of holography for more exact definition of the module of elasticity E for specific materials will be given. In conjunction with this theme a new holographic method "The Step Hologram" with which the measurement range of the holographic interferometry can be widered to approximatly factor 10...20 times will be discussed. The Step Hologram allows separation of the elastic-linear lines from elastic-non-linear lines respectively and from plastic deformation. As an application excample, the exact measurement of the E-module for a brittle material such as Porcelin will be given. This material has been specifically chosen for its elastic properties. Porcelin is a white plastic material which, like Gypsum presents practical usable results. Porcelin however unlike Gypsum is not so succeptable to breakage.
