Abstract

Section titled ā€œAbstractā€

Wide-field quantum sensing and imaging with solid-state spins has attracted wide interest for its ability to detect relative physical quantities with high sensitivity at nanoscale. However, the optical diffraction limit hinders the improvement in spatial resolution. In this work, we utilize blind structured illumination microscopy to perform wide-field quantum sensing with nitrogen-vacancy (NV) center in diamond. Without the requirement of prior knowledge of excitation light field, the spatial resolution of NV centers imaging is enhanced by 1.8-fold in comparison with conventional microscopy. Combined with spin manipulation and detection, super-resolution NV center sensing is subsequently performed to reveal the optical and electrical properties of nanodevice. The high spatial resolution and feasibility of this work will promote the applications of quantum sensing in nanoscience.
