The cavity length change of the FPI caused by the magnetostrictive probe is directly coupled into the OEO loop. Through injection locking, a precise mapping from magnetic field-induced frequency shifts to phase variations is realized, and the phase noise of OEO at near-carrier is greatly suppressed, enabling low-noise phase demodulation in the low-frequency range. A phase sensitivity of 21.4 mrad\/\u03bcT and a magnetic field resolution of 0.97 nT\/Hz\n                    <jats:sup>1\/2<\/jats:sup>\n                    at 100\u2009Hz are achieved, and the relationship between sensitivity and injection ratio is also experimentally investigated.
