title = "An omnidirectional measurement technology of CPT magnetometer based on coupling of the dark state",
abstract = "The magnetometer which is based on the coherence population trapping theory, works by exciting atoms with two modulated coherent light fields and obtaining magnetic resonance signals containing magnetic field intensity information. In view of the problem of measuring blind area in this scheme, the direction characteristics of CPT resonance signal are analyzed. A dark state coupling measurement scheme based on two groups of modulated light fields is proposed. The system performance based on this scheme is verified by the all-optical sensing experiment system. Experimental results show that the resonance signal with higher signal to noise ratio could be obtained by using the dark state coupling measurement technology. This effectively eliminates the blind area of the CPT magnetometer and avoids losing lock of system. As a result, sufficient system stability performance could be obtained in omnidirectional measurement of magnetic field.",
