  The nitrogen vacancy (NV) center in diamond has been widely applied for
quantum information and sensing in last decade. Based on the laser polarization
dependent excitation of fluorescence emission, we propose a super-resolution
microscopy of NV center. A series of wide field images of NV centers are taken
with different polarizations of the linear polarized excitation laser. The
fluorescence intensity of NV center is changed with the relative angle between
excitation laser polarization and the orientation of NV center dipole. The
images pumped by different excitation laser polarizations are analyzed with
Monte Carlo method. Then the symmetry axis and position of NV center are
obtained with sub-diffraction resolution.
