中文摘要	文章提出了一种针对再入式光纤陀螺(Re-FOG)的信号检测方法,采用正负交替变化的脉冲波调制,使不同循环圈数干涉信号得到不同的相位调制,从而分离出所需圈数的干涉信号并解算出转速。实验测试了陀螺样机,分离了第一圈和第二圈干涉信号并由此测量到转速。实验结果表明:所提出的信号检测方法能够有效地测出陀螺转速;所研制的光纤陀螺的零偏稳定性优于4°/h。; The Re-entrant Fiber Optic Gyro(Re-FOG) is a new kind of Fiber Optic Gyro(FOG),which makes the two counter-propagating lights reenter the Sagnac Sensitive Ring(SSR).In this paper,a novel signal detection method for Re-FOG is presented.With the tow counter-propagating lights being modulated by a series of pulses,the interference signals of different number rounds of circling get different phase modulation.By this method of modulation,the signals of different number rounds of circling can be separated to get the rotation speed of the gyroscope.Signals of 1 round and 2 rounds of the gyroscope are experimentally separated,and the rotation speed of the gyroscope is detected.The experimental results show that the signal detection method is practical,and the bias stability of the Re-FOG is less than 4�/h.
