Abstract

A setup is presented allowing simultaneous application of ESPI and holographic double exposure interferometry in the study of microdeformations of climatically stressed natural stones. High sensitivity to deformations is obtained by introducing a suited reference fringe system, while high spatial resolution is achieved using the real image for evaluation. Problems of the method are discussed and several example applications to natural stones are described.
