Abstract
A sensor device for magnetic field measurement using optical magnetic resonance measurement (ODMR) includes a sensor device for magnetic field measurement using ODMR, including a diamond having a plurality of nitrogen defects, a laser emitter, a photodetector, and a circuit board. The laser emitter is designed for the fluorescence excitation of the nitrogen defects, and the photodetector is designed to receive fluorescence radiation of the nitrogen defects. The circuit board has a plurality of layers comprising at least one inner layer; the laser emitter is disposed on an upper face of the circuit board; the photodetector is disposed on a lower face of the circuit board; the diamond is disposed in the interior of the circuit board in the plane of extension of the at least one inner layer; and at least one of the layers has current-carrying structures designed to produce a homogeneous magnetic field which is oriented perpendicularly to the layers of the circuit board and which permeates the diamond.
