He-Ne气体压强和比例对塞曼激光陀螺偏频特性影响

Influence of He-Ne Pressure and the Ratio on Biasing Value of Zeeman Laser Gyroscope

进行了He-Ne气体对激光陀螺偏频特性影响的理论与实验研究。理论推导发现,激光陀螺内部He-Ne气体对其偏频量有重要影响,He-Ne气体比率一定时,偏频量与其内部压强成线性关系。在不同气压下对激光陀螺偏频量与压强的关系进行了实验验证,实验结果与典型参数下的理论结果吻合得较好;给出了不同比率下激光陀螺偏频量与其压强的数据。

The biasing effect of Zeeman laser gyroscope affected by He-Ne gas was studied theoretically and experimentally. It is found by theoretical analysis that the He-Ne gas considerably affects the biasing value of the gyroscope,which indicates that the value linearly depends on the pressure of the gas with the constant ratio. The biasing value was measured under different pressures,and the comparison between the theoretical result and the measurement shows good agreement,and it verifies the validity of the theoretical model. The research provides basis for choosing the intensity of pressure of He-Ne gas, which is practically important for Zeeman laser gyroscope design consideration.
