Abstract

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.
