An effective method for enhancing the sensitivity of interferometric fiber-optic gyroscope (IFOG) is presented. Light waves propagate twice along the same sensing coil made of polarization-maintaining fiber in different polarization states by inducing a fiber polarization splitter/combining in the IFOG. Preliminary performance data of a gyro prototype exhibits 0.006°/h bias stability.
提出了一种提高干涉型光纤陀螺（IFOG）灵敏度的有效方法。通过在 IFOG 中引入光纤偏振分光/合路器，使光波以不同的偏振态在同一保偏光纤传感线圈中两次传播。陀螺原型样机的初步性能数据显示，偏置稳定性为 0.006°/h。
