Towards Polarization-Insensitive Coherent Coded Phase OTDR
Sterenn Guerrier, Christian Dorize, Elie Awwad +1
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-…

Introducing Coherent MIMO Sensing, a fading-resilient, polarization-independent approach to phase-OTDR
Sterenn Guerrier, Christian Dorize, Elie Awwad +1
Nowadays, long distance optical fibre transmission systems use polarization diversity multiplexed signals to enhance transmission performance. Distributed acoustic sensors (DAS) us…
