Abstract
An optical system comprises a multicore fiber comprising at least two cores of which each core comprises at least one Fiber Bragg Grating. The optical system also comprises a force transducing element being bendable in one or more directions and being fixed to the multicore fiber so as to transduce force applied to the force transducing element to the multicore fiber, resulting into a bending and/or compression and/or tension of the multicore fiber. The multicore fiber is connectable or connected to a measurement system for optically measuring the response of at least one Fiber Bragg Grating, for each of at least 2 cores of the multicore fiber, as a result of the multicore fiber bending and/or compression and/or tension for deriving a characteristic of the force acting on the position of the force transducing element of the optical system.
