Abstract

This study introduces a novel quasi-distributed sensing system that utilizes identical weak polarization maintaining-fiber Bragg gratings (PM-FBGs) and resonance frequency mapping (RFM) for simultaneous strain and temperature measurements. By considering the differences in cavity length change response based on the polarization axes.
