Compensation of phase noise impairments in distributed acoustic sensors based on optical pulse compression time-domain reflectometry
Piñeiro Ben, Enrique; Sagüés García, Mikel ; Loayssa Lara, Alayn (IEEE, 2023) Artículo / ArtikuluaWe introduce a method to compensate for the deleterious effects of the phase noise of the laser source on long-range distributed acoustic sensors (DAS) that implement optical pulse compression (OPC). Pulse compression can ... -
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 ekarpenaWe 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 ekarpenaWe 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. -
