Title (EN) OPTICAL FIBER SENSING DEVICE FOR SENSING THE DISTRIBUTION OF THE COMPRESSION DEFORMATION OF A COMPRESSIBLE OR DEFORMABLE ELEMENT
(FR) DISPOSITIF DE DÉTECTION DE FIBRE OPTIQUE POUR DÉTECTER LA RÉPARTITION DE LA DÉFORMATION PAR COMPRESSION D'UN ÉLÉMENT COMPRESSIBLE OU DÉFORMABLE
Abstract:
(EN) The invention relates to an optical fiber sensing device (1 ) for sensing the distribution of the compression/deformation of a compressible/deformable element (2), comprising: an incompressible/undeformable tubular element (3) with a recess (4) extending in a length direction (X) thereof, the recess being enclosed by the tubular element, an optical fiber (5) arranged in the recess, comprising one or more light distortion structures (6), and being expandable in the length direction of the recess, one or more expandable elements (8), having a higher compressibility/deformability than the tubular element in a transverse direction (Y), arranged at one or both ends (9) of the tubular element, the optical fiber being enclosed in the expandable elements, which are arranged for expanding/contracting in the length direction, along with the optical fiber, when the expandable elements are subjected to a transverse load (F).
(FR) L'invention concerne un dispositif de détection de fibre optique (1) pour détecter la répartition de la compression/déformation d'un élément compressible/déformable (2), comprenant : un élément tubulaire incompressible/non déformable (3) avec un évidement (4) s'étendant dans une direction de longueur (X) de celui-ci, l'évidement étant entouré par l'élément tubulaire, une fibre optique (5) disposée dans l'évidement, comprenant une ou plusieurs structures de distorsion de lumière (6), et étant extensible dans la direction de la longueur de l'évidement, un ou plusieurs éléments expansibles (8), ayant une compressibilité/déformabilité supérieure à celle de l'élément tubulaire dans une direction transversale (Y), disposés à une extrémité ou aux deux extrémités (9) de l'élément tubulaire, la fibre optique étant enfermée dans les éléments expansibles, qui sont agencés pour s'étendre/se contracter dans la direction de la longueur, conjointement avec la fibre optique, lorsque les éléments expansibles sont soumis à une charge transversale (F).
