Abstract

A distributed fiber optic sensor for localization and identification of a disturbance along an optical fiber is presented. The sensor is based on a double-loop Sagnac interferometer. Any disturbance causing phase shift for a frequency up to 20000 Hz may be detected and localized by the sensor with a simple configuration of an optic system.
