We introduce a technique to compensate the performance impairments due to the laser phase noise in long-range pulse-compression DAS sensors. Experiments demonstrate the use of the longest duration pulse compression waveform ...
We demonstrate the use of two-wavelengths to enhance the dynamic range in phase-sensitive OTDR vibration sensors. The system overcomes the phase wrapping con- strains by the synthesis of an equivalent wavelength measurement.
Long-range and high-resolution traffic monitoring based on pulse-compression DAS and advanced vehicle tracking algorithm We demonstrate traffic monitoring over tens of kilometres of road using an enhanced distributed acoustic sensing system based on optical pulse compression and a novel transformed-domain-based processing scheme with enhanced ...
