Holographic Interferometry

This work presents the principles and methods of holographic interferometry, a coherent-optical measurement technique for deformation and stress analysis, for the determination of refractive-index distributions, or applied to non-destructive testing. Emphasis is placed on the quantitative computer-aided evaluation of the holographic interferograms. Based upon wave-optics, the evaluation methods, their implementation in computer-algorithms, and their applications in engineering are described.
