Publisher's Synopsis
This text presents a unified interpretation of holographic interferometry - a very powerful technique for the measurement of small displacements, deformations and stresses which has found application in various domains of experimental mechanics. Using a physical and synthetic approach, the authors describe each method, pointing out its dependence on certain physical principles, as well as its eventual connection and relationship with similar methods.;Employing a straightforward style, mathematics is kept to a minimum and the level of physics is as simple as possible. Examples of applications of holographic interferometry to particular engineering problems are included to clarify the theory. Special emphasis is placed on the applications of the method to fracture mechanics, as holographic interferometry has been found to be particularly efficient in stress intensity factor evaluation.
