Abstract

In this research, we present a method for enhancing the precision and reliability of r esonance frequency mapping (RFM) measurements in optical fiber sensor based systems for assessing strain and temperature in various sensing targets. The results demonstrate that employing balanced photodetectors effectively suppresses noise originating from the sensor signal within the RFM system.
