A novel strain sensor based on a pair of fiber Bragg grating comb filters

摘要：

A pair of fiber Bragg grating (FBG) comb filters with different channel-spacings are designed and fabricated to measure strain. The reflection peaks of one comb filter shift when the strain changes. And the other comb filter is used as calibration standard. The two comb filters have different channel-spacings, 1.00 nm and 0.95 nm, which can be regard as the structure of vernier caliper. In our experiment, the strain resolution is about 41.7 με, with low demand of the demodulation devices. And it could be greatly improved further in terms of Gaussian fitting technology of the peaks’ intensity.
