【摘要】：在采用低偏和保偏混合光路的混偏光纤陀螺的光学架构中,包含了一些单模光纤元件和单模光纤。当单模光纤发生弯曲时,光纤中传输的纤芯导波模式和单模光纤中的界面反射波模式之间将会发生相互干涉,导致光的传输特性受到影响。提出了单模光纤弯曲对光纤陀螺标度因数稳定性影响的数学模型。仿真和实验结果表明:当温度发生变化时,单模光纤弯曲会导致传输光的中心波长发生漂移和振荡,从而影响光纤陀螺标度因数稳定性。中心波长振荡的振幅与弯曲半径直接相关。
[Abstract]:In the optical architecture of a hybrid fiber optic gyroscope (fog) with a low and a polarization-maintaining hybrid optical path, some single-mode fiber elements and single-mode optical fibers are included. When the single mode fiber is bent, the core guided wave mode transmitted in the fiber and the interface reflection wave mode in the single mode fiber will interfere with each other, which will affect the transmission characteristics of the light. A mathematical model of the influence of single mode fiber bending on the stability of scale factor of fiber optic gyroscope is presented. The simulation and experimental results show that when the temperature changes, the bending of single-mode fiber will lead to the drift and oscillation of the central wavelength of the transmitted light, thus affecting the stability of the scale factor of the fiber optic gyroscope. The amplitude of the central wavelength oscillation is directly related to the bending radius.
