SYSTEMS AND METHODS FOR RESONATOR FIBER OPTIC GYROSCOPES UTILIZING REFERENCE RING RESONATORS

摘要

Systems and methods for fiber optic gyroscopes are provided. In one embodiment, a resonator fiber optic gyroscope (100) comprises: first and second laser sources (110,112) producing first and second optical beams (101,102); a first resonator (120) having a hub comprising a hub material, wherein the first and second optical beams circulate within the first resonator in opposite directions; a second resonator (140) having a hub comprising the hub material, wherein the first and second optical beams circulate within the second resonator in opposite directions; first and second servo loops (130,150) ; the first loop controls the first laser source based on a beam that has circulated through the first resonator and a beam that has circulated through the second resonator; the second servo loop controls the second laser source based on a beam that has circulated through the first resonator and a beam that has circulated through the second resonator; and a rotation rate detection circuit.
