20 dB SNR enhancement in phase-sensitive OTDR using pulse stretching and recompression
25th International Conference on Optical Fiber Sensors, 2017, Jeju, Corea del Sur. ; This work shows the possibility of using chirped pulse amplification concepts in order to increase the signal-to-noise ratio (SNR) of phase sensitive optical time domain reflectometry (ΦOTDR) sensors. This method allows to increase the SNR of a ΦOTDR sensor without sacrificing spatial resolution. Here, we report a ΦOTDR sensor with a spatial resolution of 3 mm (limited only by the available detection equipment) and an SNR increase of 20 dB over the traditional architecture. To our knowledge, this is the highest-resolution ΦOTDR sensor reported to date. ; European Commission ; Ministerio de Economía y competitividad ; Comunidad de Madrid
