Summary: | A system for magnetic detection includes a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers, a magnetic field generator that generates a magnetic field that is applied to the NV diamond material, a radio frequency (RF) excitation source that provides RF excitation to the NV diamond material, an optical excitation source that provides optical excitation to the NV diamond material, an optical detector that receives an optical signal emitted by the NV diamond material, and a controller. The controller is configured to compute a total incident magnetic field at the NV diamond material based on the optical signal emitted by the NV diamond material, and drive the magnetic field generator to generate a compensatory magnetic field, the generated compensatory magnetic field being set to offset a shift in the optical signal emitted by the NV diamond material caused by an external magnetic field. |
