激光陀螺稳频精度对比例因子的影响研究
Effect of Frequency Stability on Scaling Factor of Ring Laser Gyro
摘要
激光陀螺比例因子的修正量是其一项重要的误差源,为深入研究此修正量的实际大小,文章针对某型激光陀螺进行了理论计算及实验验证,得到了比例因子在不同腔频下的调谐曲线。实验数据表明,对比例因子精度要求不超过1×10-7时,则稳频的影响比较小,这对稳频电路的设计具有一定的参考意义。
Abstract
The scale factor correction is one of the important error sources of ring laser gyro. To get the specific magnitude of correction, theoretical arithmetics and experimental verifications in allusion to one kind of ring laser gyro are discussed in this paper, and the tuning curve of the scale factor with different cavity frequencies is obtained. Test results indicate that the influence of the frequency stability can be ignored if the precision requirement of the scale factor is less than 1×10-7.
