Abstract

L'invention concerne un ensemble plaquette de détection destiné à surveiller l'activité acoustique ou le mouvement d'un objet disposé sur ladite plaquette. Cet ensemble plaquette de détection fait intervenir un capteur à fibres optiques amélioré comme élément de transduction de pression afin de convertir les fluctuations de pression en un signal de sortie qui se modifie en fonction des fluctuations de pression. Grâce à la conception améliorée du capteur, la zone de fusion du coupleur peut être infléchie sans être mise sous tension. Dans un mode de réalisation préféré, la zone de fusion du coupleur est arrangée sensiblement en forme de U, de sorte que les fils à fibres optiques du capteur soient adjacents les uns par rapport aux autres, sur un côté du capteur.
