摘要：
We propose a POTDR setup and investigate the Rayleigh scatter and Fresnel refection. A piezoelectric polarization controller (PPC) is applied in this setup. Based on the transfer matrix theory of the PPC, the state of polarization (SOP) of the Fresnel reflection is analyzed under different temperature. In the experiment, we find that when any part of the fiber is affected by the temperature, the SOP of Fresnel reflection will be changed.
