Abstract

Based on a cavity-length tunable fiber-loop resonator, a multibeam optical path difference is generated. It can be used to match and correlate the reflective signals from the partial reflective ends of each sensing fiber gauge. The correlation signals correspond to the sensing gauge lengths, and the shift of the correlation peak is related with the fiber sensing gauge elongation caused by strain or temperature. Therefore, it can be used to measure distributed strain or deformation for smart structural monitoring.
