1 INTRODUCTION

Optical fiber sensors are emerging as an important application of optoelectronic systems. During the 30 or more years since they were first proposed [1], they have matured from a concept into a technology that—typically for sensor systems—is finding important niche applications.

In this chapter, we first introduce the basic concepts that underpin the operation of optical fiber sensors. There are many, and virtually every optical effect has been used in a sensory context. Second, we give a more detailed consideration of specific applications and technologies. Chapter ...
