Abstract
In this paper, a novel heterodyne detection technique of rotation rate is described. This technique uses highly birefringent single-mode fiber and an electrooptic frequency shifter for a heterodyne interferometric system, and thus releases the use of acoustooptic devices and also the nonreciprocity which usually exists in a heterodyne fiberoptic gyroscope. Initial experimental results show a good linearity of the scale factor.
