ABSTRACT:
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.
