Abstract
Section titled āAbstractāThe nitrogen-vacancy color centers in diamond can be used as an excellent magnetic sensor. In this work, we present a wide-field planar magnetic imaging technique based on nitrogen-vacancy color centers. Through optically detected magnetic resonance (ODMR) which is readout from a scientific CMOS camera to extract resonance frequency, we experimentally reconstruct the magnetic field distribution of permanent magnets and particles of magnetite (Fe <sub xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>3</sub> O <sub xmlns:mml=āhttp://www.w3.org/1998/Math/MathMLā xmlns:xlink=āhttp://www.w3.org/1999/xlinkā>4</sub> ). The imaging field of this technology can reach the sub-millimeter level and the spatial resolution can reach the optical diffraction limit. The presented wide-field NV imaging technique offers wide-field imaging, high spatial resolution, and high magnetic sensitivity.
