Abstract

Diamond nitrogen-vacancy (NV) center quantum magnetic sensors show great potential for high-precision magnetic field measurement, but their complex, bulky discrete systems limit high-voltage electrical applications. This paper designs a compact “optical input-electrical output” sensing probe (3.12cm 3 ) integrating optical excitation, fluorescence collection, and photoelectric conversion. With optimal magnetic sensitivity of 4.92nT/Hz 1 / 2 , average 6.5nT/Hz 1 / 2 , and low standard deviation (0.8nT/Hz 1 / 2 ), it resolves insulation, anti-interference, and power consumption bottlenecks, enabling high-voltage equipment magnetic field monitoring.
