Vector magnetometry has various applications in navigation systems, precision metrology, and life sciences. Recently, optically detected magnetic resonances (ODMR) based on negatively charged nitrogen-vacancy (NV−) color centers in diamond have been developed as a platform for magnetic sensing. However, most approaches require knowledge of the crystal axes and need an external magnetic bias field to measure the field’s orientation or they rely on the use of single NV− centers and require volumetric data sets. Here, we show vector magnetometry based on polarometric ODMR on ensembles of NV− color centers without bias field [1]. By avoiding the complex dataset, we will be able to reach fast data acquisition, with implications for video-rate vector magnetometry.
