	1	High-sensitivity, high-spatial-resolution distributed strain sensing based on a poly(methyl methacrylate) chirped fiber Bragg grating显示文摘In this study,a high-sensitivity,high-spatial-resolution distributed strain-sensing approach based on a poly(methyl methacrylate)chirped fiber Bragg grating(CFBG)is proposed and experimentally demonstrated.Linearly chirped FBGs in a polymer optical fiber provide an alternative to the silica fiber owing to the lower Young’s modulus,which can yield a higher stress sensitivity under the same external force.According to the spatial wavelength-encoded characteristic of the CFBG,a fully distributed strain measurement can be achieved by optical frequency-domain reflectometry.Through time-/space-resolved short-time Fourier transform,the applied force can be located by the beat frequency originated from the space-induced time delay and measured by the differential frequency offset originated from the strain-induced dispersion time delay.In a proof-of-concept experiment,a high spatial resolution of 1 mm over a gauge length of 40 mm and a strain resolution of 0.491 Hz/μεwere achieved.
