摘　　要：扁平式光纤陀螺的合理光纤环设计对提高小型化程度和精度具有重要现实意义。提出了嵌套式多层多匝光纤环设计思路。首先,介绍了光纤陀螺仪小型化设计途径、嵌套式多层多匝光纤环的设计结构与原理。其次,对光纤环进行了建模计算和模拟仿真。结果表明:嵌套式多层多匝光纤环可以在扁平式光纤陀螺同样空间和布局内增加更多的光纤长度,从而比一般光纤环有更高的检测精度,仿真出的精度提高的范围在38%~61%之间。仿真表明,零偏漂移也有一定提高。在相同精度要求情况下,嵌套式多层多匝光纤环可以将扁平式光纤陀螺尺寸设计的更小,高效利用空间。Reasonable fiber ring design of flat fiber-optic gyroscope is of great practical significance to improve miniaturization and precision.The design idea of nested multi-layer and multi-turn optical fiber ring is put forward.Firstly,the miniaturization design approach of fiber-optic gyroscope,the design structure and principle of nested multi-layer and multi-turn fiber ring are introduced.Secondly,the optical fiber ring is modeled and simulated.The results show that the nested multi-layer and multi-turn optical fiber ring can increase the length of optical fiber in the same space and layout of the flat fiber-optic gyroscope,so that it has higher detection precision than the general optical fiber ring,and improvement of simulated precision is range of 38%~61%.Simulation results show that the zero bias drift is also improved to some extent.Under the same precision requirement,the nested multi-layer and multi-turn fiber ring can make the flat fiber-optic gyroscope smaller in size and use space efficiently.
