Abstract

The usage of holographic interferometry, speckle and moire methods for 3-D stress-strain analysis is considered. The influence of refraction in nonhomogeneously deformed media on the fringe formation is demonstrated. The calculations of this effect were done using an inversion method based on Radon transform and multidirectional holographic interferometry. Dependencies of the accuracy of the reconstruction in the steep gradient region for the limited number of projections are illustrated in solving the contact problem.
