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 7):
The system of  claim 1 , further comprising:\n a first Faraday rotator and a first half wave plate; a second Faraday rotator and a second half wave plate; wherein the first reflector is a first polarizing beam splitter, and the first Faraday rotator and the first half wave plate are in at least one optical path between the first beam splitter and the first polarizing beam splitter; wherein the second reflector is a second polarizing beam splitter, and the second Faraday rotator and the second half wave plate are in at least one other optical path between the second beam splitter and the second polarizing beam splitter; wherein the first polarizing beam splitter is configured to optically couple a first polarization component having a first polarization to a second photodetector; and wherein the second polarizing beam splitter is configured to optically couple a second polarization component having a first polarization to a third photodetector.
