LMMSE-Based Phase Estimator for Fiber-Optic Coherent Spread-Spectrum FBG-Based Sensing Systems
Yiyang Bai, Élie Awwad, Michèle Wigger
Fiber Bragg grating (FBG)-based sensing enables localized strain and temperature monitoring by tracking the phase changes of the light reflected from FBGs inserted along a fiber. A…
Distributed Acoustic Sensing Over Deployed Telecommunication Fiber Networks: Opportunities and Challenges
Élie Awwad, Maria Freire Hermelo, Diane Prato +5
In this paper, we highlight opportunities and challenges of deploying Rayleigh-based distributed optical fiber sensing, also known as distributed acoustic sensing (DAS), over exist…
Comparative Analysis of Spread-Spectrum Codes for Fibre-Optic Distributed Acoustic Sensing
Maria Freire-Hermelo, Elie Awwad
This paper presents a comprehensive performance comparison of several coded sequences for distributed acoustic sensing systems through numerical simulations. Correlation analysis r…
Numerical Model of a Multiple-Input-Multiple-Output Distributed Acoustic Sensing System with Joint Phase and Birefringence Estimation
Diane Prato, Mehran Mokhtari Sheramin, Renaud Gabet +1
In this work, we introduce and experimentally validate a numerical model for a Multiple-Input-Multiple-Output Distributed Acoustic Sensing (MIMO-DAS) system that accounts for dynam…
