摘要
讨论了在光纤陀螺系统中测量相位调制器半波电压的两种新方法,并进行了误差分析。测得的矿用Ti:LiNbO_3波导相位调制器半波电压U_=1.83V,误差小于0.1V,实验结果与理论分析一致。
Two novel methods for measuring the half-wave voltage of crystal electro-optic phase modulator in Gyro are described. The measurement errors are analysed. By experiment we obtained the half-wave voltage of Ti:LiNbO_3 waveguide phase modulator U=1.83V. Its error is less than 0.1V. The experiment results are in accordance with the theoretic analysis.
