摘要:
随机游走系数是衡量闭环光纤陀螺性能水平的重要指标,其体现了陀螺的极限精度。分别从理论上分析了偏置工作点、入射光功率对光纤陀螺随机游走系数的影响。根据随机游走系数中各部分噪声源的特性,建立了闭环光纤陀螺偏置工作点、入射光功率与随机游走系数的数学模型。模型表明设定合适的光功率与偏置工作点可大大提升闭环光纤陀螺精度性能。通过实验验证了模型的正确性,实验结果表明提升光功率并采用陀螺的最优偏置工作点,可大幅提升陀螺随机游走性能。
Abstract:
The random walk coefficient(RWC) is one of the most important performance indexes for fiber optic gyroscopes (FOG); it represents the ultimate precision of FOGs. This paper analyzed the relationship between modulation depth, incident light power, and RWC. A mathematical model was established according to the characteristic of noise. The model indicated that by setting the appropriate modulation depth and incident light power it is possible to see significantly better precision performance. The experimental results agreed with the mathematical model. Therefore, it was determined that the RWC could be reduced by increasing light power and employing an optimum modulation depth as compared with traditional parameters.
