A Simple and Novel Passive Double-Sensitivity Optical Gyroscope Based on Non-Reciprocal Polarization Techniques
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 arrange…
