Paper Abstract

This paper describes a novel configuration of a distributed optical fiber stress sensor based on a Sagnac ring construction. The principle of operation is based on the FMCW technique. The intensity and location of a stress applied to the fiber can be determined simultaneously by detecting the amplitude and the frequency of the beat signal which is produced by two forward-coupled mode beams in the Sagnac ring. The system was found to have a spatial resolution of 1 meter in a sensing range of 50 meters.
