In this paper current techniques used in sensitive photoelectric imaging devices are investigated. An ideal imaging device is defined in terms of parameters that are directly related to the properties of a real device. Characteristics of a real device such as resolution, detectivity, and quantum efficiency are discussed in terms of basic device construction. The design of several types of image tubes that have found applications in astronomy are discussed in detail. The tubes are compared with regard to several performance parameters including resolution, detectivity, and information capacity. Some attempt is also made to consider such practical aspects as cost, complexity, and availability. Several specific experiments are described that were performed on one of the image tubes discussed--the secondary electron conduction tube. Finally, a concise summary of the present status of image devices for astronomy is given and some prospects for future improvements are discussed. (Author).

The past decade has seen a major resurgence in optics research and the teaching of optics throughout the major universities both in this country and abroad. Electrooptical devices have become a challenging form of study that has penetrated both the electrical engineering and the physics departments of most major schools. There seems to be something challeng ing about a laser that appeals to both the practical electrical engineer with a hankering for fundamental research and to the fundamental physicist with a hankering to be practical. Somehow or other this same form of enthusiasm has not previously existed in the study of photoelectronic devices that form images. This field of, endeavor is becoming more and more so phisticated as newer forms of solid state devices enter the field not only in the data processing end but in the conversion of radiant energy into electrical charge patterns that are stored, manipulated, and read out in a way that a decade ago would have been considered beyond some fundamental limit or other. It is unfortunate, however, that this kind of material has heretofore been learned only by the process of becoming an apprentice in one or more of the major development laboratories concerned with the manufacture of image intensifiers or television tubes or the production of systems employing these devices.

This open access book gives a complete and comprehensive introduction to the fields of medical imaging systems, as designed for a broad range of applications. The authors of the book first explain the foundations of system theory and image processing, before highlighting several modalities in a dedicated chapter. The initial focus is on modalities that are closely related to traditional camera systems such as endoscopy and microscopy. This is followed by more complex image formation processes: magnetic resonance imaging, X-ray projection imaging, computed tomography, X-ray phase-contrast imaging, nuclear imaging, ultrasound, and optical coherence tomography.

This volume is written for those who desire a comprehensive analysis of the latest developments in infrared detector technology and a basic insight into the fundamental processes which are important to evolving detection techniques. Each of the most salient infrared detector types is treated in detail by authors who are recognized as leading authorities in the specific areas addressed. In order to concentrate on pertinent aspects of the present state of the detector art and the unique point of view of each author, extensive tutorials of a background nature are avoided in the text but are readily available to the reader through the many references given. The volume opens with a broad-brush introduction to the various types of infrared detectors that have evolved since Sir William Herschel's discovery of infrared radiation 175 years ago. The second chapter presents an overall perspective of the infrared detector art and serves as the cohesive cement for the more in-depth presentation of subsequent chapters. Those detector types which, for one reason or other have not attained wide use today, are also discussed in Chapter 2. The more notable and widely used infrared detectors can be divided into three basic classes which are indicative of the primary effect produced by the photon-detector interaction, i.e., thermal, photoconductive, photo voltaic, and photoemissive. Chapters 3, 4, and 5 offer a detailed treatment of each of these important processes.

Concentrator Photovoltaics (CPV) is one of the most promising technologies to produce solar electricity at competitive prices. High performing CPV systems with efficiencies well over 30% and multi-megawatt CPV plants are now a reality. As a result of these achievements, the global CPV market is expected to grow dramatically over the next few years reaching cumulative installed capacity of 12.5 GW by 2020. In this context, both new and consolidated players are moving fast to gain a strategic advantage in this emerging market. Written with clear, brief and self-contained technical explanations, Handbook of Concentrator Photovoltaic Technology provides a complete overview of CPV covering: the fundamentals of solar radiation, solar cells, concentrator optics, modules and trackers; all aspects of characterization and reliability; case studies based on the description of actual systems and plants in the field; environmental impact, market potential and cost analysis. CPV technology is at a key point of expansion. This timely handbook aims to provide a comprehensive assessment of all CPV scientific, technological and engineering background with a view to equipping engineers and industry professionals with all of the vital information they need to help them sustain the impetus of this encouraging technology. Key features: Uniquely combines an explanation of the fundamentals of CPV systems and components with an overview of the market place and their real-life applications. Each chapter is written by well-known industry specialists with extensive expertise in each particular field of CPV technology. Reviews the basic concepts of multi-junction solar cells and new concepts for CPV cells, highlighting the key differences between them. Demonstrates the state of the art of several CPV centres and companies. Facilitates future cost calculation models for CPV.
