摘要
分析了宽谱光源的平均波长对标度因数的影响,初步建立了开环光纤陀螺和闭环光纤陀螺标度因数的系统模型,详细讨论了平均波长和光纤陀螺第二闭环影响标度因数的机理,并进行了相关的实验,实验结果与理论分析结果吻合,验证了该系统模型的正确性。
The influence of the mean wavelength of a broad-spectral source on the scale factor is analyzed. The systematic models of the scale factors for the open-loop and closed-loop fiber optic gyroscopes are preliminarily established. The mechanism influences of the mean wavelength and the second feedback loop on the scale factor are discussed in detail. The corresponding experiments are conducted. The experimental results coincide well with the theoretical analysis results and the validity of the proposed systematic model is verified.
