Super-resolution Airy disk microscopy of individual color centers in diamond

Understand

Super-resolution imaging techniques enable nanoscale microscopy in fields such as physics, biology, and chemistry.

• However, many super-resolution techniques require specialized optical components, such as a helical-phase mask.
• We present a novel technique, Super-resolution Airy disk Microscopy (SAM) that can be used in a standard confocal microscope without any specialized optics.
• We demonstrate this technique, in combination with ground state depletion, to image and control nitrogen-vacancy (NV) centers in bulk diamond below the diffraction limit.
