Abstract
Some methods and configurations are disclosed for high bandwidth acquisition of magnetometer data with increased sensitivity. Some embodiments provide for increased bandwidth and sensitivity of the magnetometer by eliminating a reference signal for full repolarization of the magneto-optical defect center material prior to acquisition. Elimination of the reference signal eliminates the time needed to repolarize the magneto-optical defect center material and the acquisition time for the reference signal. Some implementations can include activating a radiofrequency (RF) pulse sequence to apply an RF field to the magneto-optical defect center material and acquiring a magnetic field measurement using the magneto-optical defect center material. The magnetic field measurement may be acquired independent of a reference magnetic field measurement.
