Nitrogen-vacancy (NV) centers in diamond are a leading modality for magnetic sensing and imaging under ambient conditions. However, these sensors suffer from degraded performance due to paramagnetic impurities and regions of stress in the diamond crystal lattice. This work demonstrates a quantum diamond microscope (QDM) for simultaneous mapping and spatial correlation of key properties of a millimeter-scale NV-diamond sensor chip, including: NV ensemble photoluminescence (PL) amplitude, spin-lattice relaxation time (T1), and homogeneous and inhomogeneous spin coherence lifetimes (T2 and T2^*), as well as lattice stress/strain, birefringence magnitude, and birefringence angle of the diamond crystal.
