A Novel Double-Arched-Beam-Based Fiber Bragg Grating Sensor for Displacement Measurement

Abstract

A double-arched-beam-based fiber Bragg grating (FBG) sensor for displacement measurement is presented. Unlike most FBG sensors that measure the resonance wavelength shifts to detect the measurand, this kind of FBG sensor is proposed to measure the displacement based on the demodulation of the FBG's reflective spectra bandwidth. According to the strain… (More)
