A highly sensitive accelerometer for determining the acceleration of a structure includes a mass within a housing suspended by opposing support members. The support members are alternately wound around a pair of fixed mandrels and the mass in a push pull arrangement. At least a portion of one of the support members comprises a transducer capable of measuring the displacement of the mass within the housing. An embodiment of the invention employs optical fiber coils as support members for use in interferometric sensing processes. Arrays of such interferometer based accelerometers may be multiplexed using WDM or similar methods.

La présente invention concerne un accéléromètre à haute sensibilité permettant de déterminer l'accélération d'une structure, qui comprend une masse dans un boîtier suspendue à des supports se faisant face. Ces supports sont enroulés alternativement autour d'une paire de mandrins fixes et de la masses en agencement symétrique. Au moins une partie de l'un des supports comprend un transducteur capable de mesurer le déplacement de la masse dans le boîtier. Un mode de réalisation de l'invention utilise des enroulements de fibre optique en guise de support de façon à les utiliser dans des processus de détection interférométrique. On peut multiplexer des réseaux de ces interféromètres à base d'accéléromètres en utilisant un multiplexeurs en longueur d'onde ou par des procédés similaires.
