Towards wide-field vector magnetometry — •Tofianme Sorgwe¹, Florian Sledz¹, Mario Agio^1,2, and Assegid Flatae¹ — ¹Laboratory of Nano-Optics, University of Siegen, 57072 Siegen, Germany — ²National Institute of Optics (INO), National Research Council (CNR), 50019 Sesto Fiorentino, Italy

In recent time, a development of polarimetric vector magnetometry based on nitrogen-vacancy color centers in diamond without the need for an external bias field has been demonstrated [1]. However, this approach has so far been conducted on a localized area of the sample. By employing a camera-based detection system in conjunction with broad-field illumination, this method is currently extended to generate spatially resolved maps of magnetic field across a wider sample area with a sensitivity down to µT.
