摘　　要：设计并实验了一种新的数字闭环光纤陀螺调制方式,比较了目前常用的调制方式同实验中调制方式的差异。实验结果表明,采用新调制方式的光纤陀螺能很好地实现闭环工作方式,实测到陀螺的各项性能同原调制方式相仿。但对新调制方式中更好的死区抑制效果预期,在实验中并未明显观测到。A new phase modulation method of the close-loop FOG had been designed and tested.The differences between the old and new methods had been compared.The experimental results showed that the FOG using the new phase modulation method can operated very well in the close-loop mode.The measured performances of the FOG using the new method are similar to that of the old one.But the expected small dead zone performance had not been observed in the ecperiment.
