Fully Distributed Fiber-Optic Sensing Enabled by Kalman Filtering
Juan M. Marin, Roman Ermakov, Florian Azendorf +3
Signal fading creates points along the fiber where phase cannot be extracted, so they are conventionally discarded. Instead, we propose a Kalman-based solution for ϕ-OTDR full-fibe…
Fundamentals of Optical Fiber Sensing Schemes Based on Coherent Optical Time Domain Reflectometry: Signal Under Dynamic Temperature Conditions
Roman Ermakov, Huwei Wang, Florian Azendorf +4
We present a theoretical, algorithmic, and experimental study of temperature sensing using -OTDR with coherent detection. A physics-based model is developed to relate the measur…
Multi-Modal Fiber Sensing for OffshoreEnvironmental and Infrastructure Monitoring
Konstantinos Alexoudis, Florian Azendorf, Alvaro Doval +5
Monitoring a 118 km subsea cable using Distributed acoustic, state-of-polarization, and Brillouin sensing captured storm-induced strain up to (dynamic) and $\app…
