This project aims to provide enabling technologies to manufacture high-performance and cost-effective fibre optic distributed sensing systems. Coherent optical time domain reflectometry based on Rayleigh scattering in optical fibre has been explored for distributed vibration, strain and temperature sensing. However, its susceptibility to laser phase noise, amplitude and polarisation fading hinders its widespread application. This project aims to apply the technologies developed in coherent optical communication to fibre optic distributed sensing. The research is planned to include design, simulation, and experimental verification of the proposed sensing system.

该项目旨在提供使能技术来制造高性能且具有成本效益的光纤分布式传感系统。基于光纤瑞利散射的相干光时域反射测量已被探索用于分布式振动、应变和温度传感。然而，其对激光相位噪声、振幅和偏振衰落的敏感性阻碍了其广泛应用。该项目旨在将相干光通信中开发的技术应用于光纤分布式传感。该研究计划包括所提出的传感系统的设计、仿真和实验验证。
