Abstract

We propose a revised minimum reciprocity configuration (MRC) of an interferometric all-fiber-optic gyroscope (all-fiber I-FOG), based on our design of a fused-taper polarization-maintaining fiber coupler. This MRC reduces the insertion loss and production cost of the optical path, yet maintains the principle of reciprocity. Experimental results show that this I-FOG with five optical components exhibits better performance than a conventional I-FOG with six optical components. Using the revised MRC, the angle random walk and the bias instability of an I-FOG are improved from $0.025\text{\hspace{0.17em} deg}/\surd \mathrm{hr}$ to $0.011\text{\hspace{0.17em} deg}/\surd \mathrm{hr}$, and $0.48\text{\hspace{0.17em} deg}/\mathrm{hr}$ to $0.21\text{\hspace{0.17em} deg}/\mathrm{hr}$, respectively.
