摘　　要：在四频激光陀螺高精度数字一体化电路的基础上,通过控制激光陀螺两臂放电电流差值、两臂电流和值、两对模式的光强差值分别按照预定程序进行精确的改变,从而得到以上参量与陀螺零漂之间的关系系数。对陀螺进行长时间的测试,根据实际工作中各参量的精度计算得出电路系统对激光陀螺精度的影响。实验中为保证结论的一般性,选取两个精度相差较大的激光陀螺进行实验,结果表明,在现有方式下工作的高精度数字一体化电路系统对激光陀螺精度的影响在1%以内。Based on the laser gyro digital integration circuit,the coefficients between the null shift and current discharge difference,current discharge sum,beam intensity difference are got by precision controlling the parameters changing. Through long time tests to laser gyro,the infection,caused by the precision of these parameters,is got by calculating. In order to make the conclusion validly,the two laser gyros which are different in precision are selected to be tested. The resucts show that the digital integration circuit which is working under now mode infects the precision of laser gyro no more than 1%.
