Paper Abstract

The application of holographic interferometry to determine large deformations of opaque bodies by compensating when reconstructing has been treated previously in several publications. This contribution concerns a similar investigation in the case of a domain with a strong spatial change of the index of refraction as for instance in a fluid or also in combination with different media. Firstly, the general theory about the analogy between both fields as well as the image aberration and the fringe modification is outlined. Secondly, a development of the fringe vector in the case of a moderate index gradient is performed.
