Towards Polarization-Insensitive Coherent Coded Phase OTDR
arXiv:2110.09949 · doi:10.1364/OFS.2020.T3.20
Abstract
We explore the alternatives for interrogating a fiber sensor from the polarization point of view, and demonstrate a better accuracy with dual polarization probing for coherent phi-OTDR compared with single polarization probing.
