The pursuit of more efficient telecommunications has resulted in a major research push towards communication systems that are lighter, faster, more reliable and cheaper. This has given rise to great advances in devices and in fibre optics. A spin off of this research is the development of optical sensors, which use photonic materials and concepts. Optical sensors have wide-ranging applications in various fields including telecommunications, civil engineering, chemical industry, biomedical applications and the electrical power industry. This comprehensive handbook, written by a wide spectrum of leading international researchers, offers a clear understanding of the theory as well as focusing on the many practical applications throughout the industry. The book is organised into four main sections: - * Preliminary: Offers an overview of Fiber Optic Sensing Technology, the applications where it can be used successfully and also serves as an overall introduction to the handbook. This section also analyses current publications in the field. * Fundamentals of Photonics and Components for Sensing: Describes the photonic concepts and components needed in order to carried out the understanding, the design, and to realise photonic sensor systems. * Principles and Techniques for Sensing: Provides the principles and techniques in which the photonic sensing technology is based in order to understand how sensors work and how sensors can be made. * Applications: An ample overview of the developments which are successfully taking place in laboratory and field trials, as well as the available sensors in the current market and the future trends in this field. Applications are featured throughout the text, and this section focuses primarily on niche applications. This handbook would prove to be a valuable reference resource for researchers, engineers and postgraduate students in fibre optical sensing, as well as practising engineers in optical communications and electronic engineering, civil engineering, aerospace industry, biomedicine and robotics.

This interesting book covers latest aspects of a highly sophisticated technology; results treated in critical detail; demonstrates applicability of this technology to practical problems in process control, biochip methods, clinical analysis, environmental sciences

Although noninvasive, continuous monitoring of glucose concentration in blood and tissues is one of the most challenging areas in medicine, a wide range of optical techniques has recently been designed to help develop robust noninvasive methods for glucose sensing. For the first time in book form, the Handbook of Optical Sensing of Glucose in Biological Fluids and Tissues analyzes trends in noninvasive optical glucose sensing and discusses its impact on tissue optical properties. This handbook presents methods that improve the accuracy in glucose prediction based on infrared absorption spectroscopy, recent studies on the influence of acute hyperglycemia on cerebral blood flow, and the correlation between diabetes and the thermo-optical response of human skin. It examines skin glucose monitoring by near-infrared spectroscopy (NIR), fluorescence-based glucose biosensors, and a photonic crystal contact lens sensor. The contributors also explore problems of polarimetric glucose sensing in transparent and turbid tissues as well as offer a high-resolution optical technique for noninvasive, continuous, and accurate blood glucose monitoring and glucose diffusion measurement. Written by world-renowned experts in biomedical optics and biophotonics, this book gives a complete, state-of-the-art treatise on the design and applications of noninvasive optical methods and instruments for glucose sensing.

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.
