Abstract
This Tutorial discusses the basic principles of optical fiber sensor technology, outlining the various sensing mechanisms which can be utilized to influence the propagation of light in an optical fiber. Sensor types and classifications, intensity, interferometric, intrinsic, and extrinsic, are defined, and a wide range of examples is discussed. Particular emphasis is given to describing the principles of operation of acoustic, magnetic field, and rotation (gyroscope) sensors. Distributed sensor configurations and sensor network- ing/telemetry are also outlined, and the Tutorial concludes with a brief review of the current status of fiber sensor technology.
