该文对EDFS以及超发光二极管(SLD)光源光谱的相干性和不对称性进行了分析,同时分析这种光谱不对称性造成的"四态方波调制"信号误差,提出了在"四态方波调制"闭环光纤陀螺中消除这种误差的方法,从而提高陀螺标度因数的精度和稳定性.

In this paper, the coherence and asymmetry of the EDFS and SLD spectrum are analyzed,and the four-state square wave modulation signal error caused by the spectrum asymmetry is also analyzed.A method of elimilating the error in four-states square wave biasing modulation closed loop fiber optic gyro is proposed. By using this method,the precision and stability of the scale factor of the closed loop fiber optic gyro have been improved.
