"Using lensless Fourier transform holography the problem of deblurring an out-of-focus image on a photographic transparency was studied. First a lensless Fourier transform hologram of an out-of-focus image was taken using a point reference source. By replacing this hologram into the recording plane and re-illuminating it with coherent light, the imaging wave transmitted through the hologram immediately gives, by Fourier transformation, the restored, deblurred image. A bar target was photographed out-of-focus, and using this method, with subjective analysis at 95% confidence, the deblurred image was judged better than the original. This method of image deblurring does indeed work, but the restoration process is limited by the amount the transparency was out-of-focus to begin with."--Abstract.

This textbook deals with fourier analysis applications in optics, and in particular with its applications to diffraction, imaging, optical data processing, holography and optical communications. Fourier analysis is a universal tool that has found application within a wide range of areas in physics and engineering and this third edition has been written to help your students understand the complexity of a subject that can be challenging to grasp at times. Chapters cover foundations of scalar diffraction theory, Fresnel and Fraunhofer diffraction moving onto Wave-Optics Analysis of Coherent Optical Systems and Wavefront Modulation. Joseph Goodman’s work in Electrical Engineering has been recognised by a variety of awards and honours, so his text is able to guide students through a comprehensive introduction into Fourier Optics.

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).

When Faraday performed the very first experiments on electromagnetic effects, which form the very foundation of modern civilization since virtually everything electrical utilizes them, he was asked of what use his experiments were. He is said to have replied: "What is the use of a baby?" That reply might also be given to those who asked what was the use of basic research which resulted in the development of the laser and holography. Brigadier General Leo A.Kiley, Commander, Office of Aerospace Research, USAF, in his remarks before the Society of Photo-Optical Instrumentation Engineers at the opening ceremony of the Seminar on Holography held at San Francisco, California, in May 1968, declared, "It has been said that in the twenty-first century at least half of the jobs that will exist then do not exist today. But be that as it may, I am sure that holography will be common place. " And later "Even in its embryonic state today, the concept of holography is providing real world applications to the scientific community and I feel that continued rapid growth can be predicted." Now, only three years after these statements, the development of holography is extraordinary on the scientific side and very promising from the point of view of proven and potential applica tions. Holography looks like an emerging technique, a valuable tool for engineers.

Handbook of Optical Holography is composed of 10 chapters that readers can turn to for specific questions regarding holography. This book begins by elucidating the classification of holograms, major types of holograms, and variations. The text then explains the image formation, cardinal points and principal rays for holography, equipment, and procedures. This book also tackles special problems and application areas of this technology. This text will be valuable to people who want to apply holography—whether to industry, government, health services, education, or research.

Holography has matured over the years since it was first invented by Dennis Gabor and further developed by many workers during the last decade. With some applications a commercial reality and many more continually appearing, it is now possible to compile a volume devoted to the applications of holography. This book consists primarily of papers presented at the second U.S. Japan Seminar on holography, held in Washington, D.C., from October 20-27, 1969, under the auspices of the National Academy of Sciences, National Science Foundation, and the Japanese Society for the Promotion of Science. In addition to most of the papers presented at the seminar, several others are included because they cover important applications which are appropriate to this volume. Attendance at the seminar was limited to ten delegates from each country; these delegates being chosen so as to permit the seminar to include as wide a range of subjects as possible, with each delegate being recognized as an authority in his particular field of holography. In addition, Dr. Gilbert Devey (Program 'Director for Engineering Systems for the National Science Foundation, and the one most responsible for making the seminar possible), Professor Wolf F.

Holography reviews advances in the field of holography and its various applications in areas such as interferometry, microscopy, and acoustics. Topics range from acoustic holography to image multiplexing, formation of images in holography, and holography by computer. Some experiments based on Gabor's holography are also presented. This book is comprised of five chapters and begins with an overview of the fundamentals of holography, with particular reference to spatial and temporal coherence, diffraction at finite and infinite distances, and filtering of spatial frequencies. The reader is then introduced to the principles and applications of holography, focusing on the geometric optics and aberrations of holograms as well as interferometry and microscopy. The following chapters explore how images are produced and reconstructed using a hologram and explain how to detect the differences between two images. Three main types of synthetic holograms are also considered: binary holograms, holograms with several intensity levels, and the holograms called kinoforms. The last chapter is devoted to optical filtering and pattern recognition. This monograph will be of value to physicists and researchers as well as to those interested in how holography works.

Holography exploded on the scientific world in 1964, but its slow fuse had been burning much longer. Over the next four decades, the echoes of that explosion reached scientists, engineers, artists and popular culture. Emerging from classified military research, holography evolved to represent the power of post-war physics, an aesthetic union of art and science, the countercultural meanderings of holism, a cottage industry for waves of would-be entrepreneurs and a fertile plot device for science fiction. New working cultures sprang up to mutate holography, redefining its products, reshaping its audiences and reconceiving its applications. The outcomes included ever more sublime holograms and exquisitely sensitive measuring techniques - but also priority disputes, prurience and poisonous business rivalries. New subjects cross intellectual borders, and so do their explanations. This book draws on the history and philosophy of science and technology, social studies, politics and cultural history to trace the trajectory of holography. The result is an in-depth account of how new science emerges. Based on unprecedented interviews with pioneer holographers and extensive archival research, it reveals how science, technology, art and wider culture are entwined in the modern world.
