1. A rate of rotation sensor comprising a fiber optic interferometer comprising an optical fiber comprising a core material, which is wound to form a fiber coil and into which two partial light beams of a first light source can be coupled, wherein a part of the core material of the optical fiber is embodied as a Bragg structure having a periodically varying refractive index, wherein the fiber optic interferometer is suitable for outputting signals from which physical state parameters in the interior of the fiber coil can be determined.
