Compensation of phase-noise in pulse-compression phase-sensitive OTDR sensors. 27th International Conference on Optical Fiber Sensors, Th4.40. https://doi.org/10.1364/OFS.2022.Th4.40978-1-957171-14-210.1364/OFS.2022.Th4.40https://academica-e.unavarra.es/handle/2454/45311We 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 to date.application/pdfeng© The authors © 2022 Optica Publishing Group.
