Compensation of phase-noise in pulse-compression phase-sensitive OTDR sensors
Piñeiro Ben, Enrique; Sagüés García, Mikel
; Eyal, Avishay; Loayssa Lara, Alayn (Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena 
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 ... -
Distributed strain sensing with large dynamic range based on two-wavelength phase-sensitive OTDR
Piñeiro Ben, Enrique; Sagüés García, Mikel ; Mompó Roselló, Juan José ; Eyal, Avishay; Loayssa Lara, Alayn (Optica Publishing Group, 2020)
Contribución a congreso / Biltzarrerako ekarpena
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
Corera Orzanco, Íñigo ; Piñeiro Ben, Enrique; Navallas Irujo, Javier; Sagüés García, Mikel ; Loayssa Lara, Alayn (Optica Publishing Group, 2022)
Contribución a congreso / Biltzarrerako ekarpena
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 ...
