Abstract

Fiber optic sensor technology is explained in terms of theory and applications. Two classes of sensing devices are discussed: amplitude-modulated sensors and phase-modulated sensors. Specific examples of amplitude-modulated devices--one a pressure sensor using an optical reflection technique and another an accelerometer using a microbend technique--are described. Four types of fiber optic interferometers used in phase-modulated sensors are addressed. A highly sensitive fiber optic accelerometer using a Mach-Zehnder interferometer is detailed.
