Abstract
A fiber optic sensor may be provided comprising an optical waveguide having at least one first core and a cladding surrounding the first core, wherein the first core extends substantially over the entire length of the optical waveguide and at least one Bragg grating is introduced into the first core, wherein the Bragg grating has an elongated cross section, wherein the short semi-axis is smaller than the diameter of the first core and the center of gravity of the cross section of the at least one Bragg grating lies on the axis of symmetry of the optical waveguide. A method may be provided for determining torsion with such a sensor. A method for the production of such a sensor may be provided.
