Bias Calibration of Optically Pumped Magnetometers Based on Variable Sensitivity

Bias Calibration of Optically Pumped Magnetometers Based on Variable Sensitivity

Optically pumped magnetometers (OPMs) functioning in the spin-exchange relaxation-free (SERF) regime have emerged as attractive options for measuring weak magnetic fields, owing to their portability and remarkable sensitivity. The operation of SERF-OPM critically relies on the ambient magnetic field...
