Abstract

Conjugate wave holographic interferaretry was rent1y proposed by the author for the measurerrent , in real irre, of the in-plane ccxriponents of deformation. Basical , the technique consists of recording holographical ly two syrrnetrical waves scattered by a frontally illuminated object. If the conjugates of these waves are produced and irringe on the deformed object, the in-plane displaciient fringes can be observed on its surface. After a short review of the principles of the technique , the paper presents sane examples of implementation and a number of applications. Various practical details which are relevant for the performance of the technique are pointed out and discussed.
