Holographic interferometry provides a valuable and up-to-date source of information in this rapidly expanding field. The eight specialists' contributions cover the principles and methods currently in use. The scope of the book has been limited to the study of opaque objects. Ample space has been devoted to a comprehensive treatment of the phenomena of fringe formation, with a particular emphasis on the quantitative evaluation of the holographic interference fringe patterns. The emergence of computer-aided fringe analysis and phase-shifting techniques have considerably simplified the quantitative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailed overview of full-field holographic methods for the measurement of shapes, displacements, derivatives, difference displacements and vibrations.
