Through the interferencing light intensity under a sine-wave modulation signal analysis, the output signal of fiber-optic gyroscope is demodulated. And then the change of the output signal of gyro is gotten. Through the analysis of the change we know that the effect of residuary intensity modulation on the performance of Interferometric Fiber Optic Gyroscope is related with the precision and accuracy requirements of IFOG. The higher precision, the more obvious effect.

本文首先通过正弦波调制下干涉信号光强分析解调出光纤陀螺的输出信号，进而得出残余强度调制存在的情况下陀螺输出信号的变化情况，同时，通过分析陀螺信号的变化说明残余强度调制对光纤陀螺性能的影响与陀螺精度要求有关，精度越高，其影响越明显。
