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 1):
A system, comprising:\n a first common polarizer configured to polarize a first optical signal; a first reflector configured to reflect the polarized first optical signal; a first beam splitter configured to split the reflected, polarized first optical signal into a first portion and a second portion; a second common polarizer configured to polarize a second optical signal; a second reflector configured to reflect the polarized second optical signal; a second beam splitter configured to split the reflected, polarized second optical signal into a first portion and a second portion; wherein the first beam splitter is configured to optically couple the second portion, of the reflected, polarized first optical signal, to a first photodetector; wherein the first beam splitter is further configured to optically couple the first portion, of the reflected polarized first optical signal, to a first port of an optical resonator coil; wherein the second beam splitter is configured to optically couple the first portion, of the reflected, polarized first optical signal to a second port of the optical resonator coil; wherein the first common polarizer is configured to polarize a third optical signal circulating in a first direction in the optical resonator coil; and wherein the second common polarizer is configured to polarize a fourth optical signal circulating in a second direction in the optical resonator coil.
