  • Patent number: 10466312
    Abstract: A method for detecting a magnetic field acting on a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers may include controlling an optical excitation source and an RF excitation source to apply a pulse sequence comprising two optical excitation pulses and two RF excitation pulses to the NV diamond material, receiving a light detection signal from an optical detector based on an optical signal emitted by the NV diamond material due to the pulse sequence, measuring a first value of the light detection signal at a first reference period, the first reference period being before a period of the light detection signal associated with the two RF excitation pulses provided to the NV diamond material, measuring a second value of the light detection signal at a second reference period, the second reference period being after the period of the light detection signal associated with the two RF excitation pulses provided to the NV diamond material, and computing a measurement signal based on the me

  • Patent number: 10338162
    Abstract: A system for magnetic anomaly detection is described. The system may include a nitrogen vacancy (NV) diamond material comprising a plurality of NV centers. A controller modulates a first code packet and controls a first magnetic field generator to apply a first time varying magnetic field at the NV diamond material based on the modulated first code packet. The controller modulates a second code packet and control a second magnetic field generator to apply a second time varying magnetic field at the NV diamond material based on the modulated second code packet, wherein the first code packet and the second code packet are binary sequences which have a low cross correlation with each other. The controller determines a magnitude and direction of the magnetic field at the NV diamond material, and determines a magnetic vector anomaly based on the determined magnitude and direction of the magnetic field.

  • Publication number: 20170139017
    Abstract: A system for magnetic detection may include a nitrogen vacancy (NV) diamond material, a radio frequency (RF) excitation source, an optical excitation source, an optical detector, a magnetic field generator, and a controller. The controller may control the excitation sources to apply a first pulse sequence. The controller may receive a first light detection signal due to the first pulse sequence, measure first and second values of the first light detection signal at first and second reference periods, and compute a first measurement. The controller may further control the excitation sources to apply a second pulse sequence, receive a second light detection signal due to the second pulse sequence, measure first and second values of the second light detection signal at first and second reference periods, and compute a second measurement. The first and second measurements may be based on high and low resonance frequencies of the NV diamond material.
