Quantum diamond microscope for narrowband magnetic imaging with high spatial and spectral resolution
Year: 2024
Type: article
Abstract: The quantum diamond microscope (QDM) is a versatile, widely used platform for magnetic field imaging, but in applications it has been limited to broadband signals. This study integrates a QDM with a narrowband measurement protocol and a fast lock-in camera, enabling imaging of rf magnetic field patterns with micrometer-scale spatial resolution, single-hertz spectral resolution, and nanotesla sensitivity for each pixel. The rf QDM simultaneously images the amplitude, frequency, and phase of narrowband fields, for potential applications in micrometer-scale NMR imaging, ac-susceptibility mapping, impedance tomography, electronic circuit analysis, and spatial eddy-current inspection.
