摘要：
A tunable fiber optic path difference scanner has been used to match and correlate the reflective signals from the partial reflective ends of each sensing fiber gauge. The correlation signals corresponding to the sensing gauge lengths. And the shift of the correlation peak related with the fiber sensing gauge elongation caused by the sensing fiber deformation. Therefore, it can be used to build up a multiplexed deformation sensing system to measure distributed strain or deformation for smart structural monitoring.
