Abstract

Systems and methods for compensating optical lead fluctuations in an RFOG include sources for generating first and second optical signals; an optical resonator; first and second lead lines connected to the sources and the resonator, wherein the sources couple the first and second optical signals into the first and second lead lines, and the first and the second lead lines couple the first and second optical signals into the optical resonator for propagation within the optical resonator in opposite directions; a tapping device coupled to the optical resonator that couples portions of the first and second optical signals out of the optical resonator; a combiner that combines the portions of the first and second optical signals to produce a combined output; and a photodetector that generates a beat note signal from the combined output.
