Abstract

A strain sensing system is demonstrated, consisting of a fiber Bragg grating resonator as the strain-sensing element. Signal encoding and decoding is achieved by a synthetic heterodyne technique. A strain accuracy of ± 0.426με was attained: a value comparable to that of the classical fiber Fabry Perot (FFP) sensor and higher than conventional Bragg grating strain sensing schemes. This sensing element does not suffer from fabrication problems like the FFP sensor and the interrogation problems of the conventional Bragg grating sensor.
