Physical model of optical system in interferometric fiber-optic gyro

  • 摘要: 光路系统的偏振误差极大地制约着光纤陀螺精度的提高。利用相干矩阵和琼斯矩阵对光纤陀螺中光学器件和熔接点的光学参数进行描述,建立了干涉式光纤陀螺光路系统的物理模型。与之前相关文献报道相比,该模型所表达的光路系统更加接近于工程实际。在此基础上,提出一种分析光学器件和熔接点缺陷,以及光路损耗对光纤陀螺偏振误差影响的新方法。该方法可以有效地分析光路系统缺陷对零偏和标度因数的影响,在工程上可作为评价干涉式光纤陀螺光路系统性能的一个途径。
    Abstract: The polarization error of optical system limits the accuracy of fiber-optic gyro. The models of optical devices and fused points in fiber-optic gyro are described using coherent matrix and Jones matrix. The physical model of the optical system in interferometric fiber-optic gyro is established. Compared with the former reports, the optical system described in this model is more engineering oriented. A new method is presented to analyze the polarization error caused by optical devices, fused points and the losses through the optical path. This method could analyze the influence of optical system flaws on bias and scale factor effectively, which can be used to evaluate the property of the optical system in interferometric fiber-optic gyro.
