摘 要: 谐振式光学陀螺是基于光学Sagnac效应产生的谐振频率差来测量旋转角速率的一种新型光学传感器。通过对其噪声源的研究分析,得出偏振波动是谐振式光学陀螺中的主要噪声因素之一。本文详细分析了光束中两偏振态的传输过程,建立了环形谐振腔中偏振光的通用分析模型。参照此模型,可以根据陀螺系统的结构参数获取偏振态波动情况,并选择合适的环形腔来减少偏振态的影响。

Abstract: The resonator optic gyro(ROG) is a novel inertial rotation sensor, which uses resonance frequency change due to the Sagnac effect to measure for rotating sensing. Through research on the noise sources in the ROG, the polarization fluctuation in ring resonator has shown to be one of the dominant noise sources. This paper analyzes the polarization characteristic of light propagation in ROG. A universal model is set up, which can analyze resonance curve of polarization characteristic in ring resonator. The polarization fluctuation based on the basic element parameters of the ROG can be obtained using this model. It also presents how to select a ring resonator for the smallest polarization fluctuation of the ROG.
