The use of image stabilization has grown to the point that it is now a common component of modern optical systems for imaging, communications, and remote-sensing applications. The benefits of image stabilization to astronomical research alone are so rich that it is common for astronomical telescopes, built over the last century, to be retrofitted with fast steering mirrors and tip-tilt sensors to extend their useful lifetimes. This text provides the basics of image stabilization starting with a consideration of the cause of image blurring and an introduction to the components commonly used in constructing a stabilized imaging system. With this foundation, an example image stabilized system is described and used to introduce some of the important parameters in evaluating the performance of image stabilization systems. As image stabilization systems are key components of adaptive optics systems, the more sophisticated sensing and correction devices used in this area are briefly addressed. Rather than being a mathematical, rigorous treatment of image stabilization, it provides the basic ideas in an easy-to-read format.

Computational Fourier Optics is a text that shows the reader in a tutorial form how to implement Fourier optical theory and analytic methods on the computer. A primary objective is to give students of Fourier optics the capability of programming their own basic wave optic beam propagations and imaging simulations. The book will also be of interest to professional engineers and physicists learning Fourier optics simulation techniques-either as a self-study text or a text for a short course. For more advanced study, the latter chapters and appendices provide methods and examples for modeling beams and pupil functions with more complicated structure, aberrations, and partial coherence. For a student in a course on Fourier optics, this book is a concise, accessible, and practical companion to any of several excellent textbooks on Fourier optical theory.

During much of the Cold War, America's first line of defense was in outer space: a network of secret satellites that could provide instant warning of an enemy missile launch. The presence of these infrared sensors orbiting 22,000 miles above the earth discouraged a Soviet first strike and stabilized international relations between the superpowers, and they now play a crucial role in monitoring the missile programs of China, India, and other emerging nuclear powers.Jeffrey Richelson has written the first comprehensive history of this vital program, tracing its evolution from the late 1950s to me present. He puts Defense Support Program operations in the context of world events -- from Russian missile programs to the Gulf War -- and explains how DSP's infrared sensors are used to detect meteorites, monitor forest fires, and even gather industrial intelligence by "seeing" the lights of steel mills. These satellites, reveals Richelson, detected Iran's test-firing, of a new missile in 1998 and even provided clues to the TWA 800 disaster.Drawing on many previously classified documents and on interviews with key participants, Richelson

Body MRI: Cases in Radiology serves as a ready reference of 141 cases and nearly 900 superb quality images of common and uncommon conditions encountered in the daily practice of body MRI. The book is specifically intended for radiology residents and fellows as a study guide to broaden clinical knowledge and improve diagnostic skills when reviewing MR images of the liver, biliary system, pancreas, urinary tract, adrenal glands, peritoneal cavity, spleen, gastrointestinal system, female genital tract, vascular system, and heart. The selected cases provide outstanding examples of various disease states and their appearances as demonstrated by MR imaging using a variety of pulse sequences. Each case is shown on the front page with a brief clinical history and multiple, carefully selected images that best show the important findings. When turning the page, the imaging findings, differential diagnosis and important teaching points are given in bullet-point format facilitating the learning process and allowing the reader to improve interpretation and diagnostic capability in body MRI. Cases are presented in random order to mimic the diagnostic challenges that typically occur when reading the daily worklist of cases in a routine clinical body MRI practice. Readers can also review the cases by organ system through the Index of Cases found in the back of the book.

Nuclear Medicine is a diagnostic modality which aims to image and in some cases quantify physiological processes in the body to highlight disease or injury. Within nuclear medicine, over the past few decades, major technological changes have occurred and concomitantly changes in the knowledge and skills required have had to evolve. One of the most significant technological changes has been the fusion of imaging technologies, to create hybrid systems such as SPECT/CT, PET/CT and PET/MR. With these changes in mind, Practical SPECT/CT in Nuclear Medicine provides a handy and informative guide to the purchase, clinical implementation and routine use of a SPECT/CT scanner. Practical SPECT/CT in Nuclear Medicine will be a valuable resource for all personnel working in nuclear medicine and it will be of particular value to trainees.

Although associated mostly with wireless cellular communication, CDMA is also being considered for optical channels. This text, aimed at the reader with a basic background in electrical or optical engineering, covers CDMA fundamentals: from the basics of the communication process and digital data transmission, to the concepts of code division multiplexing, direct sequence spreading, diversity techniques, the near-far effect, and the IS-95 CDMA standard form.

Affine Analysis of Image Sequences

Computer vision is a rapidly growing field which aims to make computers 'see' as effectively as humans. In this book Dr Shapiro presents a new computer vision framework for interpreting time-varying imagery. This is an important task, since movement reveals valuable information about the environment. The fully-automated system operates on long, monocular image sequences containing multiple, independently-moving objects, and demonstrates the practical feasibility of recovering scene structure and motion in a bottom-up fashion. Real and synthetic examples are given throughout, with particular emphasis on image coding applications. Novel theory is derived in the context of the affine camera, a generalisation of the familiar scaled orthographic model. Analysis proceeds by tracking 'corner features' through successive frames and grouping the resulting trajectories into rigid objects using new clustering and outlier rejection techniques. The three-dimensional motion parameters are then computed via 'affine epipolar geometry', and 'affine structure' is used to generate alternative views of the object and fill in partial views. The use of all available features (over multiple frames) and the incorporation of statistical noise properties substantially improves existing algorithms, giving greater reliability and reduced noise sensitivity.
