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 havebecome the current research hotspot. The latest research results and product technology trends of integrated fiber optic gyroscopes in the United States and Russia are sorted out, from the design and processing of integrated optical chip, the winding of micro-miniature high-symmetry optical fiber coil, and the direct coupling between integrated optical chip and micro-miniature optical fiber coil. In one aspect, the technical and technological problems faced by the integrated fiber optic gyroscope are expounded, and the solutions are analyzed. Finally, the future development trend and application prospect of the integrated fiber optic gyroscope are prospected.
