This book is the first to address the field of structurally integrated fiber optic sensors. Fiber optic sensors embedded within materials and systems are able to measure a variety of parameters (i.e. temperature, vibration, deformation, strain, etc.) that allows for real time non-destructive evaluation. Examples include the following: monitoring structural fatigue in aging aircraft or loads in bridge structures. In more advanced applications, fiber optic sensors control actuators that allow materials to adapt to their environment. This gives rise to the names, "smart," "intelligent," and/or "adaptive" materials or structures.
Structural Monitoring with Fiber Optic Technology is the firs single author book on the new field of fiber optic structural sensing. As such it provides: coverage of the fundamentals of the technology, a coherent and systematic discussion on the most important aspects of the subject, a broad view of the subject, while retaining a degree of focus on those advances most significant in terms of their future potential, particularly in regard to broad implementation of the technology. The book provides an introduction to the relevant value to structural monitoring. It also highlights the advantages of fiber optic based sensors over conventional electrical measurement technology. The book richly illustrates the subject matter with 615 figures and provides many examples of fiber optic structural sensing, including a detailed overview of a number of major field site applications. Most of these large scale applications are drawn from the civil engineering community as they have been the first to strongly embrace fiber optic structural monitoring. This is especially true for bridges, where innovative new designs and the use of fiber reinforced polymer composite materials to replace steel represents a major advance that is expected to revolutionize the construction industry. Examples include new bridges, which are serving as testbeds for these new materials and are instrumented with arrays of fiber optic structural sensors. In one case, this state-of-the-art monitoring system permits engineers at a distant site to track the response of the bridge to traffic loads and keep an eye on the long term performance of the new materials. Fiber optic structural sensing technology is equally applicable to other industrial sectors, such as the aerospace and marine industries. Indeed, several examples of ships being instrumented with arrays of fiber optic sensors are also included.

Dr. Raymond M. Measures was a Professor at the University of Toronto Institute for Aerospace Studies from 1964 to 1998, and served as the Associate Director from 1984 to 1991. In 1987, he was a member of the team that established the Ontario Laser and Lightwave Research Centre and in the early years, served on both its Board of Directors and its Management Committee. Dr. Measures played a key role in the creation of the Intelligent Sensing for Innovative Structures Network Centres of Excellence in 1995 and served as its Vice President for its firs two years. In the past decade, Dr. Measures has pioneered fiber optic structural sensing in Canada and established Fiber Optic Smart Structures Laboratory at the University of Toronto Institute for Aerospace Studies in 1988. The success of this project led to the formation of a new and vibrant company, ElectroPhotonics Corporation, which now produces state-of-the-art fiber optic telecommunication and structural sensing systems into innovative new bridges. Dr. Measures has authored or edited four books, contributed chapters to six books, an author or co-author on over 190 papers, and is a co-inventor on five patents.
