Abstract
A magnetometry apparatus includes an array of magnetometer pixels. Each magnetometer pixel includes an electron spin defect body including a plurality of lattice point defects, and a microwave field transmitter operable to apply a microwave field to the electron spin defect body. The apparatus may also include an optical source configured to emit input light of a first wavelength that excites the plurality of lattice point defects of the electron spin defect bodies from a ground state to an excited state, and a photodetector arranged to receive photoluminescence of a second wavelength emitted from a first electron spin defect body of a first magnetometer pixel of the array of magnetometer pixels. The second wavelength is different from the first wavelength.
