This book is intended for upperclass college students as an introduction to the growing field of coherent optics and to the increasing number of its applications, and also for those versed in other fields who wish to gain per spective and insight without detailed calculations. It is an outgrowth of the author's Science Study Series book Lasers and HolographY. * Besides being an updated and expanded version of that book, it includes discussions of numerous recent applications. It differs in its slightly higher analytical level and in the inclusion oflarge numbers of references, which enable the reader to obtain further information on subjects of interest to him. The level was selected to match the capabilities of students in their middle college years so as to permit them to make an early assessment of possible career interests in any of the many interdisciplinary fields now embracing the technologies of modern optics. It is hoped that the book can be used (as has occurred rather extensively with another of the author's Science Study Series books, Sound Waves and Light Wavest) as an auxiliary reading assignment for students in various disciplines. The author strongly believes that the promise of continued growth in this field, as evidenced by the extensive participation in technology develop ments by industry, both within the U. S. and abroad, identifies the subject as * Doubleday, 1969 (hard cover and paperback).

The laser's range of application is extraordinary. Arthur Schawlow says, "What instrument can shuck a bucket of oysters, correct typing errors, fuse atoms, lay a straight line for a garden bed, repair detached retinas, and drill holes in dia monds?"O The laser's specifically biomedical uses cover a similarly broad and interesting spectrum. In this book, I have endeavored to convey some of the fas cination that the laser has long held for me. It is my hope that both clinicians and researchers in the various medical and surgical specialties will find the book a use ful introduction. Biologists, particularly molecular biologists, should also find a great deal of relevant information herein. This volume's distinguished contributors provide admirably lucid discussions of laser principles, instrumentation, and current practice in their respective special ties. Safety, design, capabilities, and costs of various lasers are also reviewed. We have aimed to create a practical text that is comprehensive but not exhaustive. Our emphasis on the practical, rather than the esoteric, is dictated not only by the short history of biomedical laser use, but by the extent of the community to which this information will appeal.

Industrial Applications for Optical Data Processing and Holography discusses modern optics applications in the industrial setting. Holography and speckle metrology are emphasized through numerous examples where interferometry has been applied to gage displacements and velocities in solids and in fluids. Other detailed discussions of optics applications include fringe interpretation, pattern recognition, and the fine points of recording optical disturbances. New, successful techniques are carefully examined to analyze the aspects responsible for their success. The book also features an extensive index that will be indispensable for helping stress analysts locate specific applications. Its detailed reference lists will provide a solid reference resource for engineers and designers seeking additional information.

The fourth volume in a history of photography, this is a bibliography of books on the subject.

Lists citations with abstracts for aerospace related reports obtained from world wide sources and announces documents that have recently been entered into the NASA Scientific and Technical Information Database.
