Breaking through the bandwidth barrier in distributed fiber vibration sensing by sub-Nyquist randomized sampling
Jingdong Zhang, Tao Zhu, Hua Zheng +3
The round trip time of the light pulse limits the maximum detectable frequency response range of vibration in phase-sensitive optical time domain reflectometry (ϕ-OTDR). We propose…

Modulated Pulses Based High Spatial Resolution Distributed Fiber System for Multi-Parameter Sensing
Jingdong Zhang, Tao Zhu, Huan Zhou +3
We demonstrate a hybrid distributed fiber sensing system for multi-parameter detection. The integration of phase-sensitive optical time domain reflectometry (Φ-OTDR) and Brillouin…
