摘    要:针对采用质子交换式波导和全保偏光路的光纤陀螺,利用双波束干涉法将光纤环圈中存在的与偏振模式相关的干涉场进行了分析,推导出每种干涉场对主干涉波的幅度及相位扰动的表达式。在此基础上分析了一些关键参数对陀螺偏振噪声的影响,提出抑制光路中寄生偏振干涉场的建议。

关 键 词:光纤陀螺  偏振光  干涉  数学模型

Abstract:Interference of polarized light in optical fiber coil was analyzed by Dual Lightwave Interference Theory for FOG with PE waveguide and PM fiber. Expressions about amplitude and phase of the disturbed lightwave were individually deduced to every kind of interference. The relationship between polarization noise and important parameters were figured out and some advises about how to restrain this kind of noise in interferometric FOG were given.
Keywords:fiber optic gyro  polarized light  interference  math model
