From the preface: "The first chapter of the book gives the introduction of the fiber optic sensors. The basic instrumentations required for fiber sensor are the optical fiber, light source and the detection system. In chapter 2 to 4, describe briefly fiber optics, light sources and detectors respectively. Chapter 5 is devoted to the optical fiber sensors utilizing evanescent field absorption phenomenon. The sensors that do not require any reagent for absorption of light are discussed in this chapter. There are many chemical parameters that require the mediation of a reagent for their detection. Such kinds of sensors are described in chapter 6. The modulation of light in terms of intensity, phase, frequency, wavelength and polarization occurs in fiber optic sensors. Chapters 7 to 10 are devoted to fiber optic sensors based on wavelength, phase, polarization and frequency modulation, respectively. In chapters 11 and 12, sensors utilizing fiber bragg grating and surface plasmon resonance phenomenon have been described. One of the most important advantages of optical fiber sensors is the distributed sensing. It enables the measurement of a physical or a chemical parameter as function of position along the length of an optical fiber, and hence provides a unique capability to measure spatial variations of these quantities. Such systems are finding applications in industrial and environmental sensing. Chapter 13 is devoted to the distributed sensors. In the last chapter, simple, easy to make intensity modulated sensors have been described. The book should meet the requirements of students of science and engineering who are willing to work or are working in the area of fiber optic sensors."
