Diamond-Based Magnetic Imaging with Fourier Optical Processing
Magnetic sensing and imaging using ensembles of nitrogen-vacancy (N-$V$) centers in diamond recently have found application in disciplines as wide-ranging as condensed matter physics, biology, and paleomagnetism. However, distinguishing the signals from the four inequivalent N-$V$ orientations requires an external magnetic field, which can hinder the study of some magnetic …
