摘要：
This letter presents a high resolution multiplexed strain sensor for quasi-static strain measurement based on p-phase-shifted fiber Bragg gratings (p-PSFBGs). The sensor array is composed by four p-PSFBGs in parallel with different delay lines, and a time-division multiplexing scheme is proposed to interrogate the p-PSFBGs in turn. The Pound-Drever-Hall technique and the sideband interrogation method are employed to improve the resolution and the sampling rate. In the demonstrational experiment, three-channel quasi-static strain sensing is realized with a resolution better than 0.4 n epsilon and a sampling rate of 100 samples/s.
