摘      要：Nitrogen-vacancy(NV)centers in a bulk diamond are often employed to realize measurement of multiple physical quantities,which depends on orientation information of NV *** report a fast and effective method to determine the orientation of NV axis with the aid of a static magnetic *** measuring the optically detected magnetic resonance spectra,we can precisely extract the polar angle information between the NV axis and the known magnetic *** with the polar angle information of different kinds of NV centers,we employ the Nelder-Mead algorithm to get the optimal solution of the orientation of NV *** method is simple and efficient,and is easily applied in NV-based quantum sensing.
