Completely revised and reorganized while retaining the approachable style of the first edition, Infrared Detectors, Second Edition addresses the latest developments in the science and technology of infrared (IR) detection. Antoni Rogalski, an internationally recognized pioneer in the field, covers the comprehensive range of subjects necessary to un

"Among the many materials investigated in the infrared (IR) field, narrow-gap semiconductors are the most important in IR photon detector family. Although the first widely used narrow-gap materials were lead salts (during the 1950s, IR detectors were built using single-element-cooled PbS and PbSe photoconductive detectors, primary for anti-missile seekers), this semiconductor family was not well distinguished. This situation seems to have resulted from two reasons: the preparation process of lead salt photoconductive polycrystalline detectors was not well understood and could only be reproduced with well-tried recipes; and the theory of narrow-gap semiconductor bandgap structure was not well known for correct interpretation of the measured transport and photoelectrical properties of these materials"--

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.

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.

Microbolometers: Fundamentals, Materials, and Recent Developments describes the fundamentals of microbolometers, their historic evolution, operational principles and material choices. It also explains the impact of materials on the processing and development of device characteristics. Sections address various aspects of optical properties and recommend models of properties of materials of interest for the fabrication of the uncooled microbolometers. In addition, the book presents two case studies, Honeywell and Texas Instruments, that focus on the design and manufacture of microbolometers. Finally, recent developments, applications, patents and future trends are presented. The chapter on patents will summarize the strengths and weaknesses of each of the technologies.

The spectroscopy of highly charged ions plays a key role in numerous areas of physics, from quantum electrodynamics (QED) and parity nonconservation (PNC) testing to fusion and plasma physics to x-ray astronomy. Handbook for Highly Charged Ion Spectroscopic Research brings together many of the techniques and ideas needed to carry out state-of-the-a
