Abstract: A system for magnetic detection includes a magneto-optical defect center material including at least one magneto-optical defect center that emits an optical signal when excited by an excitation light; a radio frequency (RF) exciter system configured to provide RF excitation to the magneto-optical defect center material; an optical light source configured to direct the excitation light to the magneto-optical defect center material; and an optical detector configured to receive the optical signal emitted by the magneto-optical defect center material.

Abstract: A system provides light received from NV diamond material to an optical collector. The provision of light received from NV diamond material to an optical collector impacts the efficiency by which light is directed to the optical collector. The system may be employed to efficiently direct light from the NV diamond material to the optical collector.

Abstract: A sensor is described comprising an assembly allowing for the adjustment of light through a plurality of lenses to magneto-optical defect center materials. In some implementations, an initial calibration is done on the sensor system to adjust the relative position of the optical excitation assembly to a base structure to benefit the final intended purpose of the sensor The optical excitation assembly for attachment to a base structure can be described as comprising a slot configured to adjust the optical excitation assembly in a respective linear direction relative to the base structure, an optical excitation source, a lens, and a drive screw mechanism. The drive screw mechanism can be configured to adjust a position of the lens relative to the optical excitation source.
