激光技术激光陀螺速率偏频标度因数不对称性 laser technique laser gyro rate biased scale factor asymmetry

摘要

以激光陀螺输出拍频的理论公式为出发点, 分别从理论、仿真和实验三个方面分析了激光陀螺标度因数的正反转不对称性。标度因数的正反转不对称性对速率偏频激光陀螺的精度具有非常重要的影响, 分别从理论分析、数值模拟的角度比较详细地讨论了标度因数与转动方向的关系, 提出了一种在无须知道陀螺零偏和地球自转分量的情况下, 用于测量标度因数不对称性的实验方案, 通过实验得出某型激光陀螺转速绝对值为72°/s时, 标度因数正反转不对称性约为0.02×10-6。

Abstract

Based on theoretical equation of laser gyro beat output, scale factor forward-reversal rotation asymmetry of rate biased laser gyro is analyzed by theory, simulation, and experiment. Since the scale factor forward-reversal rotation asymmetry highly affects the precision of rate biased laser gyro, the relation between scale factor and rotation direction is analyzed by theory and numerical simulation, respectively, and a new kind way to measure the scale factor forward-reversal asymmetry is provided without knowing the laser gyro zero drift and earth rotation component. The experiments show that the scale factor forward-reversal rotation asymmetry of a laser gyro is approximately 0.02×10-6 with rotation rate of 72°/s.
