Holographic Interferometry: Principles and MethodsWiley, 11.04.1996 - 353 Seiten The book 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 of the book is 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. |
