Abstract
Wide-field magnetic imaging using nitrogen-vacancy (NV) centers in diamond can yield high-quality images for various applications, including biology, geology, condensed matter physics, and electronics troubleshooting. These quantum sensors yield widefield-of-view images with micron-scale spatial resolution and operate in ambient conditions. Most of the sensing work with NV centers in diamond has focused on DC and low frequency AC fields. This thesis demonstrates a wide-field magnetic imager and its capabilities with test structures of varying complexity. We overcome the challenges for measuring MHz frequency magnetic fields with a quantum frequency mixing approach.
