中文摘要:
      宽谱光源已成为干涉式光纤陀螺(I-FOG)的不二之选。理论上讲谱宽越宽,越有利于抑制I-FOG中的瑞利散射误差和克尔效应误差,但过宽的谱宽却会影响光纤陀螺标度因数的稳定性。如何选择谱宽合适的光源,是I-FOG研究中必须解决的问题。针对这一问题,该文从瑞利散射误差、克尔效应误差和光纤陀螺标度因数的稳定性出发,论述了光源谱宽对干涉式光纤陀螺的影响,分析了限制谱宽增加和减小的因素。结果表明,光源的谱宽不宜过宽或过窄,需要根据实际情况合理选择光源谱宽。
英文摘要:
      The wide-spectrum light source has become the best choice for interferometric fiber optic gyro(I-FOG).Theoretically,the wider the spectral width,the more beneficial to inhibit the Rayleigh scattering error and the Kerr effect error in I-FOG,but if the spectral width is too broad,the stability of the fiber optic gyro scale factor will be affected.It must be addressed how to choose the light source with a suitable spectral width in I-FOG study.For this fact,through analyzing the errors from the Rayleigh scatt...
