从环圈骨架的角度分析了影响高精度光纤陀螺温度漂移的几个因素。从提高光纤环圈系统内部热阻、减少或减缓热量导入以及降低光纤环圈内部温度梯度等方面对高精度光纤陀螺用环圈骨架进行优化设计,并对优化设计效果进行了相关试验验证。试验结果表明,光纤环圈保温隔热处理、环圈骨架有4层垫纤、减小环圈骨架轴向高度、减小环圈骨架表面积等优化设计对减小光纤环圈的温度漂移有明显效果。但仍需要从更多角度进行试验研究,才能更好地改善高精度光纤陀螺用光纤环圈的温度漂移性能。
From the perspective of loop skeleton, several factors that affect the temperature drift of high precision fiber optic gyroscope are analyzed. From the aspects of improving the internal thermal resistance of the optical fiber ring system, reducing or slowing the heat input and reducing the temperature gradient inside the optical fiber ring, the ring skeleton of the high-precision fiber optic gyroscope is optimized, and the related experimental results are also validated. The experimental results show that the optimized design of the optical fiber ring insulation can reduce the temperature drift of the optical fiber ring significantly by optimizing the design of the optical fiber ring ring with 4 layers of fiber mat, reducing the axial height of the ring bobbin and reducing the surface area of the ring bobbin, effect. However, experimental research is still needed from more perspectives to better improve the temperature drift performance of optical fiber ferrules for high-precision fiber optic gyroscopes.
