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 $\ddot{I}•$-OTDR with coherent detection. A physics-based model is developed to relate the measu…
