| contents | We introduce the light-sheet confocal quantum diamond microscope (LC-QDM) for widefield 3D quantum sensing with efficient confocal readout. The LC-QDM leverages light-sheet illumination and laser scanning confocal methods to enable high-resolution, high-speed 3D measurements with nitrogen-vacancy (NV) defects in diamond, combining the best of widefield and confocal modalities in a single device and eliminating the need for thin-NV-layer diamond chips. We perform simulations and measurements of NV initialization and readout times to model the anticipated performance of the LC-QDM compared to existing QDM designs. Our findings show that the LC-QDM will provide significant advantages for applications requiring limited laser power. |
