Summary : Terahertz waves, which lie in the frequency range of 0.1–10 THz, have long been investigated in a few limited fields, such as astronomy, because of a lack of devices for their generation and detection. Several technical breakthroughs made over the last couple of decades now allow us to radiate and detect terahertz waves more easily, which has triggered the search for new uses of terahertz waves in many fields, such as bioscience, security, and information and communications technology. The book covers some of the technical breakthroughs in terms of device technologies. It discusses not only the theoretical details and typical features of the technology described, but also some issues and challenges related to it. In addition, it is shown what can actually be done with the terahertz-wave technologies by introducing several successful demonstrations, such as wireless communications, industrial uses, remote sensing, chemical analysis, and 2D/3D imaging.

Summary : This book describes the current, concrete status of terahertz (THz) technology applied to scientific diagnoses of cultural heritage objects for conservation planning as well as for historical interest. It is unlike other THz-related scientific books in optics series, which only describe technologies and the physics behind them. A new method utilizing THz technology is introduced, which will help conservators and historians to analyse art objects at their museums. By using pulse echoes, THz imaging can noninvasively show internal structures such as layers in paintings and internal defects or additional pieces in objects. The biggest advantage of THz technology in heritage science is that THz waves can reveal the condition of preparation layers and supports of paintings that cannot be observed by other nondestructive testing methods, such as infrared (IR) or X-ray radiography. The condition of supports and preparation layers determine the lifetime of the paintings, so that their condition is the key factor for conservation planning. The comparison with existing classic methods for scientific analyses is extremely important in the context of introducing new technologies in any research field, since most conservators and heritage scientists have their own protocols for classic methods. This book compares THz results not only with visible cross sections obtained using destructive methods, but also mid-IR, near IR, UV, X-ray, and nuclear magnetic resonance(NMR), which are considered to be nondestructive methods. The book suggests future work that can be done by THz specialists, especially concerning the development of THz cameras, and by engineers and scientists in other fields, such as signal processing and chemistry, as well as by conservators.

Summary : The region of the electromagnetic spectrum between microwaves and infrared radiation has come to be known as the THz gap, mainly due to the lack of readily available laboratory sources and detectors. Potential applications, however, particularly in medicine, security, and communications, have led to increased activity by the mainstream physics and engineering community in recent years. The primary objective of this Field Guide to Terahertz Sources, Detectors, and Optics is to provide the reader with a concise description of the quasi-optical techniques used to design THz systems, as well as the basic principles of operation of the most common THz components in use today.

Summary : Seven years have passed since the publication of the previous edition of this book. During that time, sensor technologies have made a remarkable leap forward. The sensitivity of the sensors became higher, the dimensions became smaller, the sel- tivity became better, and the prices became lower. What have not changed are the fundamental principles of the sensor design. They are still governed by the laws of Nature. Arguably one of the greatest geniuses who ever lived, Leonardo Da Vinci, had his own peculiar way of praying. He was saying, “Oh Lord, thanks for Thou do not violate your own laws. ” It is comforting indeed that the laws of Nature do not change as time goes by; it is just our appreciation of them that is being re?ned. Thus, this new edition examines the same good old laws of Nature that are employed in the designs of various sensors. This has not changed much since the previous edition. Yet, the sections that describe the practical designs are revised substantially. Recent ideas and developments have been added, and less important and nonessential designs were dropped. Probably the most dramatic recent progress in the sensor technologies relates to wide use of MEMS and MEOMS (micro-electro-mechanical systems and micro-electro-opto-mechanical systems). These are examined in this new edition with greater detail. This book is about devices commonly called sensors. The invention of a - croprocessor has brought highly sophisticated instruments into our everyday lives.

Summary : This handbook is a comprehensive source of information on all aspects of non-destructive testing (NDT), for use by professionals, educators, and most of all, by the practitioners of testing. The art of NDT consists of dozens of methods, some classical, and some emerging. As the pace of industrial work and discovery intensifies and materials are utilized to their physical limits, the role of NDT becomes ever more important. As a result, the methods of testing are themselves evolving, and it is the intent of this book to capture this evolution. Handbook of Modern Non-Destructive Testing broadens the scope from traditional books on the subject. In addition to classical, emerging and exotic methods of evaluation, the book will also cover the use of NDT techniques in other fields, such as archaeology or resource exploration. With contributions from experts in all areas of the field, the reader will find balanced coverage of a variety of testing methods, with no bias against or endorsements of any particular method. The book treats many areas in depth, covering all aspects of testing, and will include case studies where appropriate. Additional coverage of statistical methods and their use, as well as simulations‘ role in testing and test design, are included.

Summary : This book describes important recent developments in fiber optic sensor technology and examines established and emerging applications in a broad range of fields and markets, including power engineering, chemical engineering, bioengineering, biomedical engineering, and environmental monitoring. Particular attention is devoted to niche applications where fiber optic sensors are or soon will be able to compete with conventional approaches. Beyond novel methods for the sensing of traditional parameters such as strain, temperature, and pressure, a variety of new ideas and concepts are proposed and explored. The significance of the advent of extended infrared sensors is discussed, and individual chapters focus on sensing at THz frequencies and optical sensing based on photonic crystal structures. Another important topic is the resonances generated when using thin films in conjunction with optical fibers, and the enormous potential of sensors based on lossy mode resonances, surface plasmon resonances, and long-range surface exciton polaritons. Detailed attention is also paid to fiber Bragg grating sensors and multimode interference sensors. Each chapter is written by an acknowledged expert in the subject under discussion.
