Abstract:
Bias error in a resonant fiber optic gyroscope (RFOG) is diminished by reducing polarization mismatch between a polarization Eigenstate of optical signals propagating inside of a resonator of the RFOG and the polarization of optical signals being injected into the resonator of the RFOG. The polarization mismatch is reduced by filtering the optical signals circulating in the resonator and the optical signals injected into the resonator with common polarizers.

Claim (Index 12):
A method, comprising:\n receiving a first optical signal and a second optical signal; filtering the first optical signal with a first common polarizer having a first polarization; filtering the second optical signal with a second common polarizer having the first polarization; injecting the first filtered signal into an optical resonator so that the first filtered optical signal propagates in a first direction through the optical resonator; injecting the second filtered optical signal into the optical resonator so that it propagates in a second direction through the optical resonator, which is opposite to the first direction; filtering an optical signal propagating in the first direction of the optical resonator with the first common polarizer; and filtering an optical signal propagating in the second direction of the optical resonator with the second common polarizer.
