Abstract
L’invention propose un dispositif de mesure de déplacement mécanique (10) d’au moins une pièce (50), comprenant :- au moins un capteur à fibre optique (20) comportant au moins un premier réseau de Bragg (30a) et au moins un deuxième réseau de Bragg (30b), - un organe élastiquement déformable (40) équipé du capteur (20), et- un organe mobile (60) solidaire de l’organe (40) et comprenant une première extrémité longitudinale (60a) de l’organe mobile configurée pour être fixée à la pièce (50). De plus, le premier réseau de Bragg (30a) s’étend entre l’organe mobile (60) et une première extrémité (42) de l’organe (40) et le deuxième réseau de Bragg s’étend entre l’organe mobile (60) et une deuxième extrémité (44) de l’organe (40). Le dispositif (10) comprend en outre un support fixe (70) auquel sont fixées la première extrémité (42) et la deuxième extrémité (44) de l’organe (40). Figure pour l'abrégé : Figure 2
