Abstract

It is often difficult to distinguish between undesired movements of a specimen and the surface displacements under study in experimental hologram interferometry. A simple technique is described, applicable to specimens which should exhibit only symmetrical deflections, which permits measurements from a single hologram of the symmetrical components of the deformations of the two opposite faces of the specimen, as well as the anti-symmetrical components corresponding to shifts or tilts of its plane of symmetry.
