Description

technical field [0001] The invention belongs to the optical fiber gyroscope technology, and in particular relates to an optical fiber ring packaging structure for improving the environmental adaptability of the optical fiber gyroscope. Background technique [0002] As an angle sensor, the fiber optic gyroscope has the advantages of anti-electromagnetic interference, large dynamic range, and high reliability, and is widely used in air, sky, sea, and land fields. However, the fiber optic ring as the core component is extremely sensitive to temperature, magnetic field, vibration, and water vapor. The non-reciprocal phase shift caused by the uncertainty of these environments will cause the zero bias of the fiber optic gyroscope to drift, which limits the further improvement of the performance of the fiber optic gyroscope. [0003] Isolating or weakening the impact of external temperature, magnetic field and vibration environment changes on the fiber optic ring, providing an ide...
