Abstract

In this paper, the output beat signal of the polarimetric heterodyning fiber grating laser sensor has been stabilized based on the investigation of polarization effect on the beat frequency. The short-term frequency fluctuation has been reduced from 1.5 MHz to about 0.1 MHz and the resolution of the sensors is greatly improved.
