摘要：
A fiber-optic dynamic sensing module (10) comprises a support member (12), a beam (14) extending from the support member, and a pre-strained fiber Bragg grating sensor (20) and a strain-free fiber Bragg grating sensor (22) mounted on the beam. The pre-strained and strain-free fiber Bragg grating sensors each comprise a Bragg grating inscribed in a fiber. The Bragg grating of the pre-strained fiber Bragg grating sensor is packaged more tightly along a longitudinal direction of the beam than the Bragg grating of the strain-free fiber Bragg grating sensor.
