A method of hcn gas spectrum denoising and baseline removal used for fbg interrogation

HIGHLIGHTS

  • who: XIAOJUN FAN et al. from the School of Precision Instrument and Optoelectronics Engineering, Tianjin University, Tianjin, China have published the paper: A Method of HCN Gas Spectrum Denoising and Baseline Removal Used for FBG Interrogation, in the Journal: (JOURNAL)
  • what: The authors propose an integrated method for spectral denoising and baseline removal to improve the interrogation performance.
  • how: The "multiband" CW filtering approach is used to extract the noise and baseline components efficiently.
  • future: In the near future research the EMD can be replaced by the ensemble EMD (EEMD) and . . .
