Book Description
The successful application of holographic interferometry, and an associated mathematical reduction process, to the determination of an asymmetric three-dimensional density field of an aerodynamic phenomenon is reported. An integral inversion method from the field of plasma physics was computerized, extensively evaluated and applied to the determination of functions, both axisymmetric and asymmetric, which simulate aerodynamic density fields. The application of holographic interferometry was extended to provide multiple holograms about a test region, with sufficient coverage to provide interferometric data for the successful solution of the density field. The analytical and experimental methods developed were applied to an experimental axisymmetric test field, the supersonic flow from a free jet, and shown to be comparable to a previous solution obtained by the Abel inversion method. Further, the free jet was tilted to provide a test field which was asymmetric in the plane of solution. Comparison of the resulting asymmetric solution was shown to be self-consistent with the previously obtained axisymmetric solution. (Author).

Book Description
Holographic interferometry was successfully applied to a large-scale wind tunel (40-cm x 40-cm test section) experiment on a three-dimensional flow field. The laser interferometer was set up in a schlieren bench with a pulsed-ruby laser as the light source. Both the object beam and the reference beam were collimated. The conventional double-exposure, off-axis operation was used to produce interferograms...

Book Description
This small book intends to build a bridge between the aspects of Optics and of Mechanics that are involved in the application of holographie interferometry to deformation analysis of opaque bodies. As such, it follows in some way the footsteps ofthe late Prof. H. Favre, who already in 1927 proposed to use interferometry for deformation measurements (refer to his thesis "Sur une nouveHe methode optique de determination des tensions interieures"). Many a concept also originates from the research and lectures of Prof. W. Prager in continuum mechanies, Profs. D.C. Drucker and C. Mylonas in experimental mechanics, Prof. C.R. Steele in sheH theory and Prof. W. Lukosz in physieal optics. Further stimulation arose in dis cussions about holography with Profs. R. Dändliker, J. Der Hovanesian and H. Tiziani as weH as with Drs. B. Ineiehen and F.M. Mottier. The contribution of Drs. W. Wüthrich, P. Bohler and G. Teichmann must also be acknowledged, the latter more partieularly for rendering valuable assistance on the delieate points of tensor calculus as weH as in the drawing of the figures. FuH gratitude must also be expressed to those who made the publication of this book possible: Dr. D. MacAdam who openheartedly accepted it in his series, Dr. H. Lotsch and the collab orators of Springer-Verlag, Mr. P. Hagnauer who revised the original text and Mrs. L. Wehrli whose patience was tried in carefully typing the manuscript, whieh Mr. F. Dufour read over again

Book Description
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.

Book Description
The successful application of holographic interferometry to the study of density fields around opaque bodies in wind tunnel experiments has been reported in the literature. The present report extends this technique to the study of the asymmetric flow fields encountered near the wing-fuselage junction of an aerodynamic model in the transonic flow regime. Finite fringe interferometry has been used to investigate the three dimensional density field about a partially transparent wing-body structure. The resulting asymmetric density field and shock wave structure are shown to be an accurate representation of the phenomena encountered in aerodynamic corner flow. (Author).

Book Description
Holographic Interferometry provides a valuable and up-to-date source of information in the 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 object and 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 simplified considerably the quantative real-time measurements of object shapes and deformations. The last two chapters provide a reasonably detailedoverview of full-field holographic methods for the measurement of shapes, displacements, dervatives, difference displacements and vibrations.

Book Description
This book is an introduction to holographic interferometry - a field of holography having a great number of important and practically useful ap pl ications. It is intended for special ists working in the field of optics and holography, and also for students of the relevant specialities. At present, a gr eater and greater number of mechanica 1 engi neers, tur bine designers, testers of diverse equipment, biologists, crystallographers, and so on have to do with holographic interferometry. To allow these spe cialists, who are comparatively far from optics, to master the subject too, the main content of the book is preceded by an introductory chapter treating the fundamental concepts of the interference of light, optical interferometry, holography and holographic interferometry. The following chapters deal with the fundamentals of the theory of ho lographic interferometry and of experimental equipment. The authors have set themselves the task of sharing their more than ten year of experience of work in the field of holographic interferometry with their readers. In this connection, the questions which they dealt with directly are con sidered in somewhat greater detail, as a rule, than those with which they have become acquainted only from publications on the subject. A sufficiently detailed (although far from complete) bibliography gives any interested reader an opportunity to improve his knowledge of this field.
