Chirped-pulse phase-sensitive reflectometry
X Reunión Española de Optoelectrónica (OPTOEL17), 12/07/2017-14/07/2017, Santiago de Compostela, España. ; In this work, a new distributed fiber sensor named chirped-pulse phase-sensitive OTDR is presented. It is based on a phase-sensitive OTDR using direct detection and linearly chirped pulses. The new sensor allows the dynamic and quantitative measurement of temperature/strain changes, with mK/nå resolution. The technique does not require a frequency sweep or coherent detection. It is presented the fundamentals of the sensor and measurements of temperature, vibrations and music. ; European Commission ; Ministerio de Economía y Competitividad ; Comunidad de Madrid
