Phase Encoding for Super-Resolution Magnetic Microscopy with Diamond NV Centers

Shawn Storm
Technische Universität München

Over the last two decades, NV centers have gained interest in the life sciences due to their nanoscale sensing and imaging abilities. Real-space imaging techniques with NV centers are either limited by the optical diffraction limit of approximately 400 nm or require cumbersome point-by-point scanning probe techniques for nanoscale resolution. An alternative technique in Fourier imaging from conventional magnetic resonance imaging (MRI) has been shown to go beyond this limit, however, with scanning probe microscopy. This thesis provides a proof of concept of the Fourier imaging technique with widefield microscopy. The design is simulated with the use of COMSOL Multiphysics, and the theoretical spatial resolution is discussed.
