  We demonstrate an optical far-field super-resolution microscopy using array
of nitrogen vacancy centers in bulk diamond as near-field optical probes. The
local optical field, which transmits through the nanostructures on the diamond
surface, is measured by detecting the charge state conversion of nitrogen
vacancy center. And the locating of nitrogen vacancy center with spatial
resolution of 6.1 nm is realized with the charge state depletion nanoscopy. The
nanostructures on the surface of diamond are then imaged with resolution below
optical diffraction limit. The results offer an approach to built a
general-purpose optical super-resolution microscopy and a convenient platform
for high spatial resolution quantum sensing with nitrogen vacancy center.
