High spatial resolution and low perturbation are required for mapping the electromagnetic field at the nanoscale, to provide crucial information about local light-matter interaction. Using optical superresolution microscopy for detection via a nitrogen-vacancy center in diamond, this work demonstrates far-field noninvasive sensing of the local electromagnetic field with high accuracy and a spatial resolution of approximately 50 nm. As the nitrogen-vacancy center is sensitive to various physical quantities, a multifunctional far-field quantum nanoscope is anticipated.
