Optical fibers, an important and promising material, have been the subject of intensive
research and development due to their many scientific and practical applications. They
are designed to guide light along its length by confining as much light as possible in
its core. The interaction between the propagating light with the fiber material is the
foundation of the development of various applications such as optical amplifiers, fiber
lasers, sensors etc.
In the last two years, optical networking has risen into the public consciousness
in many different ways. It has become the next great technological
thing — businesses want it, service providers want to sell it, device
manufacturers want to provide equipment, and component manufacturers
are scrambling to supply pieces and parts to all of them. At the time of
this writing, an 18-month backlog on optical fiber and some optical amplifiers
exists because of the enormous and unanticipated demand for highbandwidth

This book presents a comprehensive account of recent advances and researches in fiber optic sensor technology. It consists of 21 chapters encompassing the recent progress in the subject, basic principles of various sensor types, their applications in structural health monitoring and the measurement of various physical, chemical and biological parameters.
Since 1970, optical fiber and optical communication technologies have been rapidly
developing, causing a technology revolution in the communication industries. Due
to much lower attenuation and interference, optical fiber has many advantages over
existing copper wire in long-distance and high-demand applications. The revolution
in communication industries also significantly reduces the prices of optical
components and stimulates the development of optical fiber sensors.
The transport of radiation through a flexible, inexpensive conduit has changed our
lives inmore ways than we can imagine. The outstanding success of this concept is
embodied in the millions of miles of telecommunications fiber that have spanned
the earth, the seas, and utterly transformed the means by which we communicate.
This has all been documented with awe over the past several decades.
Optics and photonics are technical enablers for many areas of the economy, and dramatic
technical advances have had a major impact on daily life. For example, in the last decade,
advances in optical fiber communications have permitted a nearly 100-fold increase in the
amount of information that can be transmitted from place to place, enabling a societytransforming
Internet to thrive. As noted in the introduction to Charles Kao’s 2009 Nobel Prize
lecture on his work in optical fiber communications, “the work has fundamentally transformed
the way we live our daily lives.
