<p>Optical transducers are provided according to the present invention for detecting forces such as, rotation and transversal forces acting on them, wherein, for the purpose of detecting said forces, optical signals 2a are transmitted through an optical path 1f, for instance defined by an optical fiber. Moreover, polarization scrambling means 1a are provided together with polarizing means 1c, with said polarization scrambling means being adapted to render the polarization of the optical signals entering the optical path either parallel or perpendicular to the axis of polarization of said polarizing means. The polarization of optical signals 2b transmitted through the transducer is further modified as a result of forces acting on the transducer so that the optical signals exiting the transducer can be used for the purpose of detecting said forces.</p> |
