摘要
本文分析了四频差动激光陀螺由于稳频精度局限等原因造成其左右旋陀螺在增益曲线上不对称 ,并导致比例因子不对称和这种不对称的不稳定从而引入零漂的机理 ;还分析了影响它们的因素 ;并代入实验测得的稳频精度值 ,估测了产生的零漂大小。
the asymmetry of the left and right gyro's SFC caused by the default of frequency stabilization is analyzed in this paper,this asymmetry and its instability will cause the null shift and its changing of the differential laser gyro.The factors which can affect them is also analyzed;the null shift was calculated with the using of the default of frequency stabilization which was measured by a special experiment?
