In order to reduce polarization impact in remote fiber sensing, we propose a polarization-stabilized pulse correlation measurement technique using polarization scrambled pulse train (PSP), in which the polarization state of each pulse is randomized. We illustrate the principle of the stabilization technique and verify experimental generation of PSP. Moreover, we perform fiber strain measurement using PSP-based pulse correlation tele-monitoring under various polarization states on a multi-region fiber sensing system. Our results show good stability against polarization fluctuation, indicating that the technique has great potential for use in harsh environment tele-monitoring.
