High Collection Nonimaging Optics covers the many developments and the wider range of applications of nonimaging optics. This book is organized into 11 chapters that emphasize the application of nonimaging optics to concentrators for solar energy. This text begins with discussions on the development of formalisms in nonimaging optics, specifically in the use of geometrical vector flux concept, which have led to entirely different concentrator designs. These topics are followed by a description of the so-called compound parabolic concentrator, the prototype of a series of nonimaging concentrators that approach very close to being ideal and having the maximum theoretical concentration ratio. The next chapters examine the concept of the flow line approach to nonimaging concentration; the geometrical optics model of nonimaging optics; and constructional tolerances and manufacturing methods for nonimaging optical components. A chapter highlights the applications of concentrator designs to solar energy concentrations. The last chapter surveys the applications of nonimaging optics to optical system design and to instrument design, with particular reference to utilization of light sources with maximum efficiency. This book will be of great benefit to nonimaging optics scientists and design engineers.

From its inception nearly 30 years ago, the optical subdiscipline now referred to as nonimaging optics, has experienced dramatic growth. The term nonimaging optics is concerned with applications where imaging formation is not important but where effective and efficient collection , concentration, transport and distribution of light energy is - i.e. solar energy conversion, signal detection, illumination optics, measurement and testing. This book will incorporate the substantial developments of the past decade in this field. * Includes all substantial developments of the past decade in the rapidly moving field of nonimaging optics * The only authoritative reference on nonimaging optics, from the leader in the field

The world’s insatiable consumption of energy must be met with new technologies that offer alternative, environmentally conscious sources of light and power. The relatively young field of nonimaging optics is an ideal tool for designing optimized solar energy collectors and illumination optics and holds great promise in the development of solid state lighting applications. Introduction to Nonimaging Optics provides the first entry-level resource on this rapidly developing field. The book is divided into two sections: the first one deals with nonimaging optics—its main concepts and design methods. The second summarizes general concepts, including rays and wave fronts, reflection and refraction, and symmetry. The author makes a point to relate nonimaging to other popular fields, such as thermodynamics, radiometry, photometry radiation heat transfer and classical mechanics. He also provides useful examples at the end of each chapter. Introduction to Nonimaging Optics invites newcomers to explore a growing field and delivers a comprehensive reference to those already working in optics, illumination engineering or solar energy collection and concentration.

Nonimaging optics is a subdiscipline of optics whose development over the last 35-40 years was led by scientists from the University of Chicago and other cooperating individuals and institutions. The approach provides a formalism that allows the design of optical devices that approach the maximum physically attainable geometric concentration for a given set of optical tolerances. This means that it has the potential to revolutionize the design of solar concentrators. In this monograph, the basic practical applications of the techniques of nonimaging optics to solar energy collection and concentration are developed and explained. The formalism for designing a wide variety of concentrator types, such as the compound parabolic concentrator and its many embodiments and variations, is presented. Both advantages and limitations of the approach are reviewed. Practical and economic aspects of concentrator design for both thermal and photovoltaic applications are discussed as well. The whole range of concentrator applications from simple low-concentration nontracking designs to ultrahigh-concentration multistage configurations is covered. Table of Contents: Introduction / CPCs / Practical Design of CPC Thermal Collectors / Practical Design of CPC PV Concentrators / Two-Stage Nonimaging Concentrators for Solar Thermal Applications / Two-Stage Nonimaging Concentrators for Solar PV Applications / Selected Demonstrations of Nonimaging Concentrator Performance / The Importance of Economic Factors in Effective Solar Concentrator Design / Ultrahigh Concentration / Bibliography

Technical collection represents the largest asymmetric edge that technologically advanced countries such as the United States and its allies have in the intelligence business. Intelligence veteran Robert M. Clark’s new book offers a succinct, logically organized, and well written overview of technical collection, explained at a non technical level for those new to the field. Filling a void in the literature, The Technical Collection of Intelligence is the only book that comprehensively examines the collection, processing, and exploitation of non-literal intelligence information, including laser, acoustic, and infrared signals; non-imaging optical intelligence sources; and radar tracking and measurement of aerospace vehicles. A compelling final chapter addresses the substantial challenges that come with managing technical collection. A stunning full-color interior design features high quality graphics while a handy “tabs” feature keeps content at the ready. A useful list of recommended books and reports, a glossary of terms, and a list of acronyms make this guide a go-to resource. Technical Collection will prove invaluable to all source analysts, managers of technical collection, customers of intelligence, and recruiters for the intelligence community.

From his father, Charlemagne inherited only a part of the Frankish kingdom - little more than half of modern France and the Low Countries. Before his astonishing career had ended, he had conquered half of Europe and his armies had marched through Italy, Germany, and Spain. In a glittering Christmas Day ceremony in Rome, in the year 800, he was crowned the new Holy Roman Emperor. More than the heroic conqueror of Western Europe, Charlemagne was an intense and thoughtful human being. His succession of five wives brought him a palace full of children. So warm was his love for his daughters that he could never bear to see them married away from the court, even though enticing alliances with other rulers were offered them. A deeply religious man, Charlemagne became the protector of orthodox Christianity against medieval heresies. A patron of learning, he established schools and brought artists and scholars to his court to work and study. As a result, most classical literature comes down to us in copies of books made in Charlemagne's time. Here, from National Book Award winner Richard Winston, is his remarkable story.
