Moiré Interferometry Method For Numerical Simulation And Applications In Three-dimensional Metrology-3d



Authors : Mohammedi F . Bensaada S .

Abstract

The question that dominates and dictates the vision of this work is formed by the low spatial frequencies may appear in the combination of the light distribution of a periodical. The paper describes a method that allows the accurate prediction of the fringe localization in moiré. In the case of objects moving as a whole, Moiré can be applied thus as a metrological tool. The following applications are considered: study of mechanical vibrations and deformation, micro geometrical properties of surfaces. Several applications are emphasized: plane, cylindrical and spherical objects. Theoretical predictions are compared with experimental results.
