Optical interferometry is used in communications, medical imaging, astonomy, and structural measurement. With the use of an interferometer engineers and scientists are able to complete surface inspections of micromachined surfaces and semiconductors. Medical technicians are able to give more consise diagnoses with the employ of interferometers in microscopy, spectroscopy, and coherent tomography.
Originating from a one-day course, this material was expanded to serve as an introduction to the topic for engineers and scientists that have little optical knowledge but a need for more in their daily work lives. The need for interferometry knowledge has crossed the boundaries of engineering fields and Dr. Hariharan has written a book that answers the questions that new practitioners to interferometry have and haven't even thought of yet. This new edition includes complete updates of all material with an emphasis on applications. It also has new chapters on white-light microsopy and interference with single photons.
*Outstanding introduction to the world of optical interferometry with summaries at the begining and end of each chapter, several appendices with essential information, and worked numerical problems
*Practical details enrich understanding for readers new to this material
*New chapters on white-light microscopy for medical imaging and interference with single photons(quantum optics)

Basics of Holography is a general introduction to the subject written by a leading worker in the field. It begins with the theory of holographic imaging, the characteristics of the reconstructed image, and the various types of holograms. Practical aspects of holography are then described, including light sources, the characteristics of recording media and recording materials, as well as methods for producing different types of holograms and computer-generated holograms. Finally, important applications of holography are discussed, such as high-resolution imaging, holographic optical elements, information processing, and holographic interferometry.

This book is for those who have some knowledge of optics, but little or no previous experience in interferometry. Accordingly, the carefully designed presentation helps readers easily find and assimilate the interferometric techniques they need for precision measurements. Mathematics is held to a minimum, and the topics covered are also summarized in capsule overviews at the beginning and end of each chapter. Each chapter also contains a set of worked problems that give a feel for numbers.
The first five chapters present a clear tutorial review of fundamentals. Chapters six and seven discuss the types of lasers and photodetectors used in interferometry. The next eight chapters describe key applications of interferometry: measurements of length, optical testing, studies of refractive index fields, interference microscopy, holographic and speckle interferometry, interferometric sensors, interference spectroscopy, and Fourier-transform spectroscopy. The final chapter offers suggestions on choosing and setting up an interferometer.

When the first edition of "Optical Interferometry" was published, interferometry was regarded as a rather esoteric method of making measurements, largely confined to the laboratory. Today, however, besides its use in several fields of research, it has applications in fields as diverse as measurement of length and velocity, sensors for rotation, acceleration, vibration and electrical and magnetic fields, as well as in microscopy and nanotechnology.

Most topics are discussed first at a level accessible to anyone with a basic knowledge of physical optics, then a more detailed treatment of the topic is undertaken, and finally each topic is supplemented by a reference list of more than 1000 selected original publications in total.
* Historical development of interferometry
* The laser as a light source
* Two-beam interference

This is a new and greatly expanded edition of what has become one of the best-known introductions to the principles, techniques, and applications of optical holography. Where necessary, existing sections have been updated, and two new chapters, on holographic optical elements and advanced techniques in holographic interferometry, have been added. The book begins by presenting the theory of holographic imaging, the characteristics of the reconstructed image, and the various types of holograms. Practical aspects of holography are then covered (including optical systems, light sources, and recording media), as are the production of holograms for display, colour holography and computer-generated holograms. A variety of the applications of holography are then discussed in detail, such as high-resolution imaging, holographic optical elements, information storage and processing, and holographic interferometry, including vibration analysis and holographic interferometry with photorefractive crystals. This book assumes only undergraduate training in science or engineering and contains more than 1,000 selected references; anyone wishing to learn more about optical holography, as well as established researchers and engineers in this field, will find it invaluable.
