Book Description
Ten years have passed since the publication of the first edition of this classic text in April 2001. Considerable new material amounting to 100 pages has been added in this second edition. Each chapter now contains a Summary section at the end. The new material in Chapter 4 consists of a detailed comparison of Gaussian apodization with a corresponding beam, determination of the optimum value of the Gaussian radius relative to that of the pupil to yield maximum focal-point irradiance, detailed discussion of standard deviation, aberration balancing, and Strehl ratio for primary aberrations, derivation of the aberration-free and defocused OTF, discussion of an aberrated beam yielding higher axial irradiance in a certain defocused region than its aberration-free focal-point value, illustration that aberrated PSFs lose the advantage of Gaussian apodizaton in reducing the secondary maxima of a PSF, and a brief description of the characterization of the width of a multimode beam. In Chapter 5, the effect of random longitudinal defocus on a PSF is included. The coherence length of atmospheric turbulence is calculated for looking both up and down through the atmosphere. Also discussed are the angle of arrival of a light wave propagating through turbulence, and lucky imaging where better-quality short-exposure images are selected, aligned, and added to obtain a high-quality image.

Book Description
An essential reference for optical sensor system design This is the first text to present an integrated view of the optical and mathematical analysis tools necessary to understand computational optical system design. It presents the foundations of computational optical sensor design with a focus entirely on digital imaging and spectroscopy. It systematically covers: Coded aperture and tomographic imaging Sampling and transformations in optical systems, including wavelets and generalized sampling techniques essential to digital system analysis Geometric, wave, and statistical models of optical fields The basic function of modern optical detectors and focal plane arrays Practical strategies for coherence measurement in imaging system design The sampling theory of digital imaging and spectroscopy for both conventional and emerging compressive and generalized measurement strategies Measurement code design Linear and nonlinear signal estimation The book concludes with a review of numerous design strategies in spectroscopy and imaging and clearly outlines the benefits and limits of each approach, including coded aperture and imaging spectroscopy, resonant and filter-based systems, and integrated design strategies to improve image resolution, depth of field, and field of view. Optical Imaging and Spectroscopy is an indispensable textbook for advanced undergraduate and graduate courses in optical sensor design. In addition to its direct applicability to optical system design, unique perspectives on computational sensor design presented in the text will be of interest for sensor designers in radio and millimeter wave, X-ray, and acoustic systems.

Book Description
This work is concerned with optical imaging – from simple apertures to complex imaging systems. It spans the range all the way from optical physics to technical optics. For microscopists and photographers it conveys a deeper insight into the intricacies of their daily used devices. Physics and engineering students learn to understand different imaging systems and sensors as well as lenses and errors, image amplification and processing. This introduction into the topic is suitable for beginners and experienced people. It is illustrated by many practical examples and may also be used as a work of reference. The book is useful for everyone employing and assessing imaging systems in general. A special focus is given to photo camera systems.

Book Description
For the past several years a small group within the Division, which now constitutes the Image Analysis Section of the Medical Physics Branch, has been developing analytical methodology for evaluating the imaging performance of medical diagnostic x-ray systems. This includes the development and evaluation of a wide variety of methods of analysis for appraising the health impact of radiation exposure. Many aspects of this performance have substantial impact on the patient radiation dose required for a given amount of diagnostic information and on the amount and quality of that information which can be obtained. As a result of our early work, and studies of the literature in this field, we concluded that an international symposium devoted exclusively to this topic was in order. This present volume represents the culmination of our efforts toward that end. Kenneth E: Weaver, M.S. and Robert F. Wagner, Ph.D. of the Image Analysis Section and Assistant Professor David J. Goodenough, Ph.D. of The Johns Hopkins Medical Institutions.
