Abstract

Resonator fiber optic gyroscope (RFOG) based on the Sagnac effect has the potential to achieve the inertial navigation system condition with a short sensing coil. RFOG based on fiber coupled semiconductor DFB-LD with an FPGA-based digital processor is set up. We evaluate the frequency drift due to the various non-reciprocal noise sources –shot-noise; backscattering, Shupe, Kerr effect and Faraday noises are calculated theoretically with single mode fiber (corning SMF-28)as sensor coil and compared with PM fiber( HB 1500G) as sensing coil with similar parameters. Bias of the gyro which is caused by the noise source is also analysed.
