Distributed fiber sparse-wideband vibration sensing by sub-Nyquist additive random sampling
Jingdong Zhang, Hua Zheng, Tao Zhu +6
The round trip time of the light pulse limits the maximum detectable vibration frequency response range of phase-sensitive optical time domain reflectometry (ϕ-OTDR). Unlike the un…

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…
