This book describes the latest development in optical fiber devices, and their applications to sensor technology. Optical fiber sensors, an important application of the optical fiber, have experienced fast development, and attracted wide attentions in basic science as well as in practical applications. Sensing is often likened to human sense organs. Optical fiber can not only transport information acquired by sensors at high speed and large volume, but also can play the roles of sensing element itself. Compared with electric and other types of sensors, fiber sensor technology has unique merits. It has advantages over conventional bulky optic sensors, such as combination of sensing and signal transportation, smaller size, and possibility of building distributed systems. Fiber sensor technology has been used in various areas of industry, transportation, communication, security and defense, as well as daily life. Its importance has been growing with the advancement of the technology and the expansion of the scope of its application, a growth this book fully describes.

Fundamentals of Optical Fiber Sensor Technology The field of optical fiber sensors continues to expand and develop, being increasingly influenced by new applications of the technologies that have been the topics of research for some years.

This text in the series on Optical Fiber Sensor Technology provides a foundation for a better understanding of those developments in the basic science and its applications in fiber sensors, underpinning the subject today. This book builds upon the work in an earlier single volume which covered a broad area of the subject, but which now, in this, volume 1 of the series, focuses upon the fundamentals and essentials of the technology. Material which is included has been carefully reviewed and in most cases thoroughly revised and expanded to reflect the current state of the subject, and provide an essential background for the more applications-oriented content of the subsequent volumes of the series. This volume opens with a status paper on optical fiber sensor technology, by Kenneth Grattan and Tong Sun providing in it a flavor of the main topics in the field and giving an essential overview at the sort of systems which are discussed in more detail in the other chapters in the whole series. An extensive publication list of readily accessible papers reflecting these topics is included.

Optical Fiber Sensor Technology, Advanced Applications - Bragg Gratings and Distributed Sensors, builds upon the foundations of the subject in the preceding four volumes of this series, concentrating as they do upon both applications and the technology of advanced optical fiber sensors. Previous volumes have covered the fundamentals of the field, devices and systems and chemical and environmental monitoring. This volume deals with a range of highly topical sensor devices and commercial systems, with considerable emphasis upon one of the most important areas, Bragg gratings in fibers, their fabrication and applications in advanced sensor systems and the principles and use of distributed fiber optic sensors. The volume is well illustrated and referenced, pointing to hundreds of key publications accessible in the open literature. It draws upon a group of authors with an international reputation for their work in the area, carefully edited into a coherent and logical text by the editors, based on their considerable experience in the field. This book series will provide an invaluable source for researchers, engineers and advanced students in the field of optical fibers, optoelectronics and measurement and sensing.
