    Abstract: A device includes a diamond with one or more nitrogen vacancies, a light emitting diode configured to emit light that travels through the diamond, and a photo sensor configured to sense the light. The device also includes a processor operatively coupled to the photo sensor. The processor is configured to determine, based on the light sensed by the photo sensor, a magnetic field applied to the diamond.

    Abstract: A system for magnetic detection, includes a magneto-optical defect center material comprising a plurality of magneto-optical defect centers, a radio frequency (RF) excitation source, an optical detector and an optical light source. The RF excitation source is configured to provide RF excitation to the material. The optical detector is configured to receive an optical signal emitted by the material. The optical light source is configured to provide optical light to the material, and includes a readout optical light source and a reset optical light source. The readout optical light source is configured to illuminate light in a first illumination volume of the material. The reset optical light source is configured to illuminate light in a second illumination volume of the material, the second illumination volume being larger than and encompassing the first illumination volume. The reset optical light source provides a higher power light than the readout optical light source.

    Abstract: Systems and methods using a magneto-optical defect center material magnetic sensor system that uses fluorescence intensity to distinguish the ms=±1 states, and to measure the magnetic field based on the energy difference between the ms=+1 state and the ms=−1 state, as manifested by the RF frequencies corresponding to each state in some embodiments. The system may include an optical excitation source, which directs optical excitation to the material. The system may further include an RF excitation source, which provides RF radiation to the material. Light from the material may be directed through a light pipe to an optical detector. Light from the material may be directed through an optical filter to an optical detector.
