Interference fading suppression in Phi-OTDR using space-division multiplexed probes
Zhiyong Zhao, Huan Wu, Junhui Hu +5
We propose and experimentally demonstrate a novel interference fading suppression method for phase-sensitive optical time domain reflectometry (Phi-OTDR) using space-division multi…

Multi-point Dynamic Strain Sensing using External Phase Modulation-based Brillouin Optical Correlation Domain Analysis
Bhargav Somepalli, Deepa Venkitesh, Balaji Srinivasan
We report a novel technique to detect dynamic strain variations simultaneously at multiple locations. Our technique is based on Brillouin optical correlation domain analysis implem…
