Distributed acoustic sensing with linear phase measurement at 49.1 km by dual-pulse φ-OTDR

We demonstrate the performance of dual-pulse φ-OTDR system at nearby and far-away distances, i.e. at 1.2 km and 49.1 km, in detecting and linearly retrieving the acoustic signal with proper dual-pulse probe lengths.
