Abstract:

In view of the urgent need to improve the comprehensive performance of fiber optic gyroscopes in the fields of unmanned aerial vehicles, robots and automatic driving, the integrated fiber optic gyroscopes with technical advantages such as small size, high performance and low cost have become the current research hotspot. The latest research results and product technology trends of integrated fiber optic gyroscopes in the United States and Russia were sorted out. The technical and technological problems faced by the integrated fiber optic gyroscope were expounded from three aspects of the design and processing of integrated optical chip, the winding of miniature high-symmetry optical fiber coil, and the direct coupling between integrated optical chip and miniature optical fiber coil, and the solutions were analyzed. Finally, the future development trend and application of the integrated fiber optic gyroscope were prospected.
