摘要：
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.
