  • Patent number: 10359479
    Abstract: A system for magnetic detection of an external magnetic field is described. The system includes a nitrogen vacancy (NV) diamond material having a plurality of crystallographic axes, a radio frequency (RF) excitation source, an optical excitation source, an optical detector, and a controller. The RF radio frequency excitation source is configured to provide RF excitations to the NV diamond material to excite electron spin resonances corresponding to the RF excitations.

  • Patent number: 10274550
    Abstract: Magnetometers with high bandwidth acquisition of data with increased sensitivity are described herein. Increased bandwidth and sensitivity may be achieved 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. A radiofrequency (RF) pulse sequence may be activate to apply an RF field to the magneto-optical defect center material and a magnetic field measurement may be acquired using the magneto-optical defect center material. The magnetic field measurement may be acquired independent of a reference magnetic field measurement.

  • Patent number: 10228429
    Abstract: The present disclosure relates to apparatuses and methods for stimulating a magneto-optical defect material with defect centers in a magnetic detection system using a stimulation process to significantly increase magnetic sensitivity of the detection system. The system utilizes a modified Ramsey pulse sequence pair or a shifted magnetometry adapted cancellation (SMAC) pair to detect and measure the magnetic field acting on the system resulting in mitigation of low-frequency noise sources to provide improved sensor sensitivity. For a SMAC pair measurement, two different values of tau are used as well as two different values of the microwave pulse width.

  • Publication number: 20190018075
    Abstract: The present disclosure relates to apparatuses and methods to utilize techniques to simultaneously measure Ramsey pulses on a plurality of axes of the magneto-optical defect center material with defect centers. When measuring simultaneously, there is potentially no relative sensitivity loss relative to scalar measurements. Therefore, Ramsey pulses on a plurality of axes of a magneto-optical defect material with defect centers are measured while bypassing the sensitivity loss incurred with sequential measurement techniques. The axes are interrogated simultaneously while allowing for isolation of the individual responses from the signal detected from the magneto-optical defect center material. In some embodiments, the system utilizes a special Ramsey pulse sequence pair or a ‘shifted magnetometry adapted cancellation’ (SMAC) pair to detect and measure the magnetic field acting on the system.

  • Publication number: 20190018086
    Abstract: A system for magnetic detection of an external magnetic field is described. The system includes a controller configured to control components of the system. The controller is configured to control an optical excitation source and a RF excitation source to apply pulse sequences to a magneto-optical defect center material such that in the excitation pulses of a first pair of RF excitation pulses have a first phase difference, the excitation pulses of a second pair of RF excitation pulses have a second phase difference, and the second phase difference is different from the first phase difference. The controller computes a combined magnetometry curve as a function of the RF excitation frequency based on a difference between a measured value of a first light detection signal and a measured value of a second light detection signal. The controller sets the first phase difference and the second phase difference based on the combined magnetometry curve.

  • Patent number: 10168393
    Abstract: A method for providing a miniature vector magnetometer includes embedding a micron-sized diamond nitrogen-vacancy (DNV) crystal into a bonding material. The bonding material including the embedded micron-sized DNV crystal is cured to form a micro-DNV sensor. A micro-DNV assembly is formed by integrating the micro-DNV sensor with a micro-radio-frequency (RF) source, a micron-sized light source, a reference bias magnet, and one or more micro-photo detectors. The micro-DNV assembly is operable to perform vector magnetometry when positioned in an external magnetic field.
