Abstract

L'invention se situe dans le domaine du contrôle de santé intégré à l'aide de capteurs à fibre optique à réseau de Bragg. Elle concerne un tel capteur ainsi que des procédés de localisation et d'installation de ce capteur sur un support. Selon l'invention, le capteur à fibre optique à réseau de Bragg (30) comprend une fibre optique (31) dans laquelle est inscrit au moins un ensemble de motifs (33) formant un réseau de Bragg, la fibre optique comportant, en outre, un ensemble de microstructures (32) au voisinage de chaque réseau de Bragg, les microstructures étant distinctes des motifs formant le réseau de Bragg, chaque microstructure (32) étant apte à diffuser une partie d'un faisceau lumineux dans une plage de longueurs d'onde de diffusion prédéterminée.
