Holographic and speckle interferometry : a discussion of the theory, practice, and application of the techniques

In this new edition of Holographic and Speckle Interferometry the authors have taken the opportunity to expand considerably the material on applications and to include a more coherent description of a wider range of such applications. This revision reflects the rapid increase in the uses made of the basic technique that has occurred over the past few years. In addition, the bibliography has been updated to include relevant papers published since the first edition appeared. Holographic and speckle interferometry are optical techniques which use lasers to make non-contracting field view measurements at a sensitivity of the wavelength of light on optically rough (i.e. non-mirrored) surfaces. They may be used to measure static or dynamic displacements, the shape of objects, and refractive index variations of transparent media. As such, these techniques have been applied to the solution of a wide range of problems in strain and vibrational analysis, non-destructive testing (NDT), component inspection and design analysis and fluid flow visualisation. This book provides a self-contained, unified, theoretical analysis of the basic principles and associated opto-electronic techniques (for example Electronic Speckle Pattern Interferometry). In addition, a detailed discussion of experimental design and practical application to the solution of physical problems is presented. In this new edition, the authors have taken the opportunity to include a much more coherent description of more than twenty individual case studies that are representative of the main uses to which the techniques are put. The Bibliography has also been brought up to date
