Abstract

Section titled “Abstract”

We present a micrometer-resolution and millimeter-field-of-view stress imaging method for diamonds containing a thin surface layer of nitrogen vacancy (NV) color centers. In this method, we reconstruct stress tensor elements over a two-dimensional field of view from NV optically-detected magnetic resonance (ODMR) spectra. We use this technique to study how stress inhomogeneity affects NV magnetometry performance, and show how NV stress imaging is a useful and direct way to assess these effects. This new tool for mapping stress in diamond will aid optimization of NV-diamond sensing, with wide-ranging applications in the physical and life sciences.
