摘要
基于白光干涉原理,采用麦克尔逊干涉仪补偿光程差的方法,对光纤环圈内部偏振耦合做了试验研究。研究结果表明:光纤环圈绕制过程中,在光纤环圈内部引入了新增的偏振耦合点,且引入的偏振耦合点呈周期性分布;通过改进环圈的绕制工艺,可以很好地抑制新增耦合点的产生。
The polarization coupling point position and coupling intensity in fiber gyro coils was measured by using optical path compensation ability of Michelson interferometer based on white light interferometry.The results show that the polarization coupling in fiber coils increase in the process of winding and encapsulation and the position of the polarization coupling point is distributed by periodicity.And we can reduce the polar-ization coupling by improve the quadruple symmetric winding technology .
