Paper Abstract

We have proposed an optical pulse correlation remote sensing technique, which has the advantages of high accuracy and good response linearity. To eliminate the impact of polarization fluctuation on sensing signals, we use a polarization scrambled pulse train (PSP), in which the polarization state of each pulse is randomized. We measure the stability of sensing signal under polarization fluctuation in optical pulse correlation sensing with the PSP light and obtain good stability. Moreover, we demonstrate tensile strain measurement using the optical pulse correlation sensing with the PSP and confirm the linear response to the tensile strain even under polarization changing.
