Abstract
A system for determining an orientation of a nitrogen vacancy (NV) diamond material is disclosed. The system includes the NV diamond material having a plurality of NV centers, a magnetic field generator that generates a magnetic field, a radio frequency (RF) excitation source that provides RF excitation, an optical excitation source that provides optical excitation, an optical detector that receives an optical signal emitted by the NV diamond material, and a controller. The controller controls the magnetic field generator to generate a control magnetic field and controls the magnetic field generator to successively generate calibration magnetic fields. The controller successively receives light detection signals from the optical detector, stores measurement values based on the successively received light detection signals, and calculates an orientation of the NV diamond material based on the stored measurement values.
