Abstract
Optical transducers are provided for detecting forces such as, rotation and transversal forces acting on them, wherein, for the purpose of detecting the forces, optical signals are transmitted through an optical path, for instance defined by an optical fiber. Moreover, polarization scrambling means are provided together with polarizing means, with the 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 the polarizing means. The polarization of optical signals 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 the forces.
