Fringe localization in holographic interferometry

Abstract

The paper describes a method which allows the accurate prediction of the fringe localization in holographic interferometry, in the case of objects moving as a whole. The method uses the optical path concept; it is valid either in the case of spherical illumination or in the case of plane illumination. Several applications are emphasized: translations and rotations of plane and prismoid objects, with spherical illumination. Theoretical predictions are compared with experimental results.
