Long range fading free phase-sensitive reflectometry based on multi-frequency NLFM pulse
Jingdong Zhang, Hua Zheng, Tao Zhu +5
A long range phase-sensitive optical time domain reflectometer (phi-OTDR) with a multi-frequency non-linear frequency modulation (NLFM) optical pulse is proposed in this Letter. To…
