Holographic interferometry applied to the case of large deformations.
This investigation in holographic interferometry concerns an approach to a systematic quasi-compensation by appropriate optical modifications at the reconstruction in order that the fringes of interference become visible in the case of large unknown object deformations. The relevant relations are established by using the aberration theory for the image formation in combination with elementary intrinsic differential geometry.
