| contents | This paper presents a novel interferometric fiber optic gyroscope (IFOG) architecture, the Double-Sensitive Non-Reciprocal Polarization Phase Shifter IFOG (DS-NRPPS-IFOG), which introduces for the first time a fully passive phase biasing scheme capable of simultaneous operation at two quadrature points $π/2$ and $3π/2$. Building upon prior passive biasing techniques, this design uses a Non-Reciprocal Polarization-Dependent Phase Shifter (NRPPS) combined with a double-pass sensing coil arrangement to achieve both passive $π/2$ phase modulation and enhanced measurement sensitivity. The system utilizes polarization manipulation and a quarter-wave retarder to create a double-sensitive response while eliminating the need for active modulators. Simulation results demonstrate significant performance improvements, with Angular Random Walk (ARW) values up to 50x lower than those of conventional DS-IFOG systems, depending on fiber length. Moreover, the architecture enables continuous rotation measurements and offers spontaneous noise suppression by leveraging dual quadrature detection. These findings mark a major advancement toward low-power, highly stable, and compact passive optical gyroscopes for precision navigation applications. |
