激光陀螺磁特性研究

本文分析了激光陀螺磁敏感原理，研究了腔内激光束椭偏度的产生机理，设计了高消光比激光束椭偏度测量系统。实验结果表明，激光陀螺磁灵敏度大小与磁场方向有关，输出激光束的椭偏度越大，磁灵敏度越大。研究表明，通过减小输出激光束的椭偏度，可减小激光陀螺磁灵敏度，从而增强激光陀螺环境适应性，提高激光陀螺的成品率。

Research on the Magnetic Sensitivity of RLG

The paper analyses the magnetic sensitivity of RLG, researches the principle on which ellipticity of the light in the cavity is formed, and designs a high extinction ratio instrumentation system . The result shows that the sensitivity relates the airt of magnetism and that greater ellipticity conduces more significant sensitivity The research indicates that the sensitivity can be declined by controlling the ellipticity of outgoing laser beam. This method can improve the environmental adaptivity of RLG and enhance the rate of finished products.
