The book is an introduction to the rapidly emerging field of fiber optic sensors that is having significant impact upon areas such as guidance and control, structural monitoring, process control, biotechnology, geographical information systems and medicine.

The need for both intrinsic and extrinsic fiber optic sensor technologies continues to grow. To meet the demands of this fast expanding applications-driven market, Fiber Optic Sensors, Second Edition presents both the latest advances in fiber optic sensor technology, such as the application of photonic crystal fibers to fiber optic gyroscopes, and recent application opportunities, including the use of fiber optic sensors as a minimally invasive medical treatment. The new edition of this seminal work highlights the development of fiber optic sensors, while providing an overview of current methods for the construction of high-speed and high-capacity fiber optic systems. Two new chapters cover topics such as femtosecond laser illumination inscription and the growing application sector of fiber optic chemical and biological sensors. Adding significant new material, the book continues to provide a progressive history of each sensor type as well as basic principles and fundamental building blocks for practical applications in the electrical aerospace, defense and manufacturing, smart structure, undersea surveillance, medical, and gas and oil industries.

The fourth volume in a series, this work details coverage of recent developments in the field of optical fibre sensors. It describes the impact which fibre sensors are having in such areas as chemical and environmental monitoring, structural instrumentation and smart structure, process control and engineering, and specialist industrial measurements.

A self-contained discussion of fiber optics - unlike any others available. The intent of this book is to provide the reader with an overall background in fiber optic sensors. The primary focus is on the optical sensing mechanisms and various optical configurations associated with a broad range of sensing functions that include switches, counters, displacement, temperature, pressure, flow, liquid level, chemical analysis, rotation (gyroscopes), electric and magnetic field measurements, distributive sensing, and smart skins. This edition includes three new chapters, and eight others have been updated to give the reader an overall background in fiber optic sensors and information on new market opportunities. This third edition is a must have for product design engineers, system design engineers, plant engineering/maintenance staff, and anyone involved in measurement, testing, quality and standards.Contents: Fiber Optic Fundamentals Intensity-Modulated Sensors Phase-Modulated Sensors Wavelength-Modulated Sensors Digital Switches and Counters Displacement Sensors Temperature Sensors Pressure Sensors Flow Sensors Level Sensors Magnetic and Electric Field Sensors Chemical Analysis Rotation Rate Sensors (Gyroscopes) Distributed Sensing Systems Smart Skins and Structures Market Opportunities.

Plastic Optical Fiber Sensors cover the fundamentals and applications of a new class of fiber sensors. With contributions from leading academics in the area, this book covers the theory of plastic optical fiber sensors or (POFs), as well as applications in oil, gas, biotechnology, and energy fields. Using multiple examples, the editors showcase the advantageous characteristics of POFs, such as ease of handling, large diameter, inexpensive peripheral components and simple termination tools. By doing so, the editors assert that there has been a proliferation of the use of POFs in new consumer products. The book also highlights uses for building various products, such as a POF sensor for oil trucker valve monitoring, a monitoring system for high voltage substation switch, an oil leaking sensor for offshore platforms and a solar tracker for illumination. Including over 300 black and white images, this book would be highly beneficial for professionals in manufacturing as well as academics in universities, particularly those who use optical fiber sensors on a regular basis.

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.
