Abstract

Abstract : Real‐time wide‐field optical microscopy and spectroscopy of microwave fields is demonstrated using nitrogen‐vacancy (NV) centers in diamonds. By monitoring electron spin dependent fluorescence of NV centers under a continuous illumination, a microwave field is imaged with an amplitude sensitivity of ≈45 nT Hz −1/2 and a frequency sensitivity of 2.5 kHz Hz −1/2, across a 200 × 200 μm 2 imaging area with submicrometer spatial resolution.
