具有中等精度的全数字闭环保偏光纤陀螺仪

AllDigital Closed Loop Polarization Maintaining FiberOptic Gyro with Medium Precision

报道了一种采用Ｙ分支多功能集成光路和全数字处理技术的具有中等精度的闭环保偏光纤陀螺。测试结果表明，零偏稳定性为０．４（°／ｈ），在整个±３００（°／ｓ）的测量范围内，标度因数稳定性优于８００ｐｐｍ。该光纤陀螺仪结构简单，精度高，动态范围大，适合于捷联惯性组合导航系统的应用。

お? In this paper,a polarization maintaining fiberoptic gyro with Yjunction multifunction integrated optics circuit and alldigital closed loop signal processing electronics has been reported.Test results show that the bias stability is 04(°/h),and the scale factor linearity is better than 800ppm over the whole dynamic range of the FOG.This compact FOG is a very good candidate for high performance tactical grade applications.
