The present invention relates to an disturbance sensing system, in particular an optical system in which a disturbance can be inferred. The system includes: a first waveguide portion and a second waveguide portion disposed in a side to side arrangement relative to one another; launch means for launching a first signal and a second signal onto the first waveguide portion and the second waveguide portion respectively, the first and second waveguide portions being optically coupled such that each of the transmitted first and second signals travels along each of the first and second waveguides; and, combining means for combining the transmitted first and second signals so as to produce a combination signal, the first and second signals being related to one another such that a disturbance in either one of the first and the second waveguide portions can be inferred from the combination signal. The noise or other signal resulting from a disturbance applied to both waveguide portions will be at least partially suppressed.
Cette invention concerne un système de détection de perturbations, en particulier un système optique qui permet de déduire une perturbation. Le système comprend : un premier élément de guide d~ondes et un second élément de guide d~ondes agencés côte à côte ; un moyen pour lancer un premier signal et un second signal dans le premier et le second élément de guide d~ondes respectivement, les deux éléments étant couplés de manière optique de sorte que chaque signal transmis circule le long de chaque guide d~ondes ; et un moyen pour combiner le premier et le second signal transmis afin de produire un signal de combinaison, le premier et le second signal faisant l~objet d~un lien tel qu~une perturbation dans le premier ou le second élément de guide d~ondes pourra être déduite du signal de combinaison. Le bruit ou un autre signal résultant d~une perturbation appliquée aux deux éléments sera au moins en partie supprimé.
