    摘要: An angle encoder (10) is provided for determining a rotation angle of a rotating part (11) relative to a static part (12). The angle encoder (10) comprises a magnetic ring (11) having at least two magnetic poles and being attached to the rotating part (11) and, attached to the static part (12), means for measuring a magnetic field. The means for measuring the magnetic field comprise an optical fiber (13) with a fiber Bragg grating (14) coated with a magnetostrictive material. The means for measuring the magnetic field further comprise a light source (15) and an optical sensor (16), both being optically coupled to the optical fiber (13) and electronically coupled to an electronic circuit (17). The electronic circuit (17) is arranged to determine the rotation angle based on measured signals from the optical sensor (16).
