摘要
光纤陀螺仪的精度受到Sagnac相位差测量精度的限制,因此,减小相位差测量误差至关重要。通过相干函数,研究了SLD光源光谱形状及其纹波对光纤陀螺仪精度的影响,并结合实际情况进行了验证,最后给出了光纤陀螺对光源光谱的要求以及光源确定情况下陀螺的设计方向。
Using the coherence function of a superluminescent diode （SLD）, The effect of the spectrum and its ripple of a SLD on the performance of fiber-optic gyro has been researched in this paper. The simulated results agree well with the reality. The requirement for the spectrum of a SLD is described, and some design advice of fiber-optic gyro with a given SLD is presented.
