Hybrid-Mechanism Distributed Sensing Using Forward Transmission and Optical Frequency-Domain Reflectometry

Fiber-optic sensing systems based on a forward transmission interferometric structure can achieve high sensitivity and a wide frequency response over long distances. However, there are still shortcomings in its ability to position multi-point vibrations and detect low-frequency vibrations, which lim...
