Abstract
Section titled āAbstractāIn this Letter, we propose an integrated two-dimensional magnetometer module based on nitrogen vacancy centers in diamond. The sensor has a constructed area of 7.12 cm2 and exhibits a magnetic-field sensitivity of approximately 25.12 nT/Hz1/2. By placing anti-microwave shield nets optimizing interference distance, the integrated scheme eliminates the effects of microwave interference on the amplifier. We propose the fixed-frequency optical detection of magnetic resonance, which is used to measure the relation between the magnetic field and the photoluminescence by scanning the magnetic field. Without relying on the lock-in technique, we developed an algorithm for analyzing the magnetic noise based on the PL noise analysis.
