摘　　要：介绍了一种新型光纤陀螺仪—再入式光纤陀螺仪(Re-FOG)的工作原理,这种新型陀螺仪通过缩短光纤长度克服了温度和应力引起的误差。在研制陀螺仪样机的基础上,进行了实验研究。实验结果表明,使用短光纤可实现等效多倍长度的普通光纤陀螺的检测,文中所研制的陀螺零偏稳定性优于4°/h,达到中等精度水平。In this paper the principle of a novel fiber optic gyroscope （FOG）, Re-entrant Fiber Optic Gyro （Re-FOG）, is introduced. The Re-FOG may lower the thermal-induced and stress-induced noise by using a shorter SSR. Based on the development of the prototype Re-FOG, some experiments on Re-FOG were conducted. The experimental results show that the Re-FOG can detect the rotation of the FOG using a short SSR, to get an equivalent result the ordinary FOG will need a several times longer SSR. The zero bias stability of the gyroscope is less than 4° / h, which is the medium level accuracy.
