| 摘 要： | 光纤陀螺小型化是光纤陀螺发展的一个重要方向，提出了一种基于时分复用技术的三轴光纤陀螺光路结构，通过复用一个光源和一个探测器大大减少了器件数量，有效地降低了成本，减小了体积。针对三轴光纤陀螺单信道多信号传感理论进行分析，给出了一种有效的信号提取方案，最后对光路串扰噪声进行了研究，提出一种噪声抑制技术并进行了实验验证。测试结果表明，噪声抑制技术效果良好，陀螺精度满足工程应用要求。

| Abstract: | The miniaturization is very important for fiber optic gyroscope development.A fiber optic gyro optical structure is presented based on time-division multiplexing technology.By using complex with a light source and a detector,the number of the device,the cost,and the size were reduced greatly.The single-channel and multi-signal sensing theory of three-axis fiber optic gyroscope is studied,and an effective signal extraction method is given.The optical crosstalk noise is analyzed and noise suppression technique is also given.Finally,the three-axis fiber optic gyroscope is test.The test results show that noise suppression technology works well and the gyroscope satisfies the engineering applications. |
