【摘要】 谐振式光纤陀螺是基于光学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。通过对其噪声源的大量研究表明 ,偏振波动是谐振式光纤陀螺中的主要噪声因素之一。我们主要就偏振波动的产生机理及相应的补偿措施进行了详细分析。更多还原

【Abstract】 The resonator fiber optic gyro (R-FOG) 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 R-FOG polarization-fluctuation in the resonator has shown to be one of the dominant noise sources. This paper analyzes the factor of polarization problem and the countermeasures in detail.更多还原
