CSIC; Martín-López, Sonia CSIC ORCID; Nuño, Javier CSIC ORCID; Corredera, Pedro CSIC ORCID; Ania Castañón, Juan Diego CSIC ORCID; Thévenaz, Luc; González-Herráez, Miguel CSIC ORCID | Fecha de publicación: | 2012 | Editor: | Optical Society of America | Citación: | Journal of Lightwave Technology 30: 1060-1065 (2012) | Resumen: | Raman assistance in distributed sensors based on Brillouin optical time-domain analysis can significantly extend the measurement distance. In this paper, we have developed a 2 m resolution long-range Brillouin distributed sensor that reaches 100 km using first-order Raman assistance. The estimated uncertainty in temperature discrimination is 1.2 °C, even for the position of worst contrast. The parameters used in the experiment are supported by a simple analytical model of the required values, considering the main limitations of the setup. © 2012 IEEE. | URI: | http://hdl.handle.net/10261/81743 | DOI: | 10.1109/JLT.2011.2168807 | Identificadores: | doi: 10.1109/JLT.2011.2168807 issn: 0733-8724 |
