Abstract

Section titled ā€œAbstractā€

Compared to other systems, diamond NV color centers have the advantage of being small in size and can be optically polarized and read out at room temperature. At the same time, its electron spin can interact with a variety of physical quantities, thus forming a multifunctional quantum sensor. At the same time, the excitation and detection of diamond NV color centers are usually not demanding on physical conditions, which makes them highly practical. Based on this, this paper discusses the new quantum precision measurement technology based on NV color centers for ultra-high voltage (UHV) DC measurements, and analyzes the influence of the complex environmental magnetic field on the measured components of the ODMR spectrum in the UHV converter station by the NV color-centered energy level structure and the jump mechanism and the diamond NV color-centered magnetic resonance technology for optical detection. The simulation results show that the surface receiving power of the scheme is 63% of the incident light power, which realizes the high precision measurement of the current and has high sensitivity and stability.
