“…The main function of the microwave system is to provide a homogeneous microwave field for manipulating the electron spin of the diamond NV center. The microwave scanning system consists of a microwave source and an antenna, utilizing the high uniform microwave radiation characteristics we have developed to input a 94% resonant microwave field with a power of 30 dBm to the diamond NV center [ 29 , 30 ]. The fluorescence collection system mainly consists of an objective lens, a CCD camera, and a computer, transforming fluorescence signals into ODMR signals and calculating magnetic field and temperature information.…”

This article introduces a spatial angle measuring device based on ensemble diamond nitrogen–vacancy (NV) center optical detection magnetic resonance (ODMR). This device realizes solid-state all-optical wide-field vector magnetic field measurements for solving the angles of magnetic components in space. The system uses diamond NV center magnetic microscope imaging to obtain magnetic vector distribution and calculates the spatial angles of magnetic components based on the magnetic vector distribution. Utilizing magnetism for angle measuring enables non-contact measuring, reduces the impact on the object being measured, and ensures measurement precision and accuracy. Finally, the accuracy of the system is verified by comparing the measurement results with the set values of the angle displacement platform. The results show that the measurement error of the yaw angle of the system is 1°, and the pitch angle and roll angle are 1.5°. The experimental results are in good agreement with the expected results.
