Fast Sensing of Temperature and Strain along Optical Fiber based on Brillouin Scattering
To improve the extraction accuracy, the Savitzky-Golay filter is used to filter the noisy Brillouin spectra. Based on the obtained relatively accurate Brillouin frequency shift, the symmetric part of the Brillouin spectrum is selected according to the raw Brillouin spectrum. Based on the selected sp...
