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.

Abstract: Systems, controllers, and configurations are disclosed for providing precisely timed laser actuation, RF waveform control, and synchronous acquisition of fluorescence information from magnetometry components, such as a DNV sensor. A controller for a DNV sensor may include a RF waveform generator for generating a RF waveform for a RF signal for a DNV sensor and a digital control for controlling a laser for the DNV sensor. The RF waveform generator and the digital control may be formed in a single chip, such as an FPGA or ASIC.

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 measured first and second values. Such method may further may further comprise measuring a third value of the light detection signal at a signal period, the signal period being after the first reference period and before the second reference period. Such method may further comprise computing the measurement signal based on a difference between the average of the first and second values and the third value.

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.
