| description | The fibre-optic sensor according to the invention includes a multi-mode optical fibre (1) which has a curved part for forming a mode coupling section (2), means (5) for supplying a first end of the optical fibre with coherent light, means (6) for collecting a part of the light transmitted, downstream of the mode coupling section, and means (10) for detecting characteristic variations of the part of the light received.
le capteur à fibre optique selon l'invention comporte une fibre optique multimodes (1) ayant une partie courbée pour former un tronçon de couplage de modes (2), des moyens (5) pour alimenter une première extrémité de la fibre optique en lumière cohérente, des moyens (6) pour recueillir une partie de la lumière transmise en aval du tronçon de couplage de modes, et des moyens de détection (10) de variations de caractéristique de la partie de lumière recueillie. |
