Title (EN) FIBER OPTIC DISTRIBUTED VIBRATION SENSING WITH DIRECTIONAL SENSITIVITY
(FR) DÉTECTION DE VIBRATIONS DISTRIBUÉES DE FIBRE OPTIQUE AVEC SENSIBILITÉ DIRECTIONNELLE
Abstract: front page image
(EN)Methods for determining separate velocity components of an acoustic wavefield that are incident on a distributed fiber optic sensor are disclosed. A fiber optic sensor includes fiber that is spatially distributed in non-parallel planes of a three-dimensional volume having three orthogonal axes. The fiber includes a first fiber pattern that is spatially distributed within a first plane of the three- dimensional volume, and a second fiber pattern that is spatially distributed within a second plane of the volume. The fiber patterns are interrogated separately by a distributed fiber optic interrogation system. The individual responses from each pattern are combined and processed to determine separate velocity components of the acoustic wavefield relative to the orthogonal axes of the three-dimensional volume.
(FR)La présente invention concerne des procédés pour la détermination de composantes de vitesse séparées d'un champ d'ondes acoustiques qui sont incidentes sur un capteur de fibre optique distribuée. Un capteur de fibre optique comporte une fibre qui est spatialement distribuée dans des plans non parallèles d'un volume tridimensionnel ayant trois axes orthogonaux. La fibre comporte une première forme de fibre qui est distribuée spatialement dans un premier plan du volume tridimensionnel, une seconde forme qui est distribuée spatialement dans un second plan du volume tridimensionnel. Les formes de fibre sont interrogées séparément par un système d'interrogation de fibre optique distribuée. Les réponse individuelles provenant de chaque forme sont combinées et traitées pour déterminer des composantes de vitesse séparées du champ d'ondes acoustiques par rapport aux axes orthogonaux du volume tridimensionnel.
