Construction and Characterization of a Quantum Diamond Microscope
PúblicoThe Quantum Diamond Microscope (QDM) is a novel instrument that utilizes Nitrogen-vacancy centers in diamond to image magnetic fields via Optically Detected Magnetic Resonance (ODMR) spectroscopy. A QDM is constructed and a study of its components and principles of operation is carried out. The effects of varying laser power, microwave power, and bias magnetic field on the ODMR spectrum are studied experimentally. From these studies, optimal experimental parameters for taking magnetic field measurements with this QDM were determined to be at least 3W of laser power and -15dBm of microwave power. The effect of data collection time on the measured background noise was also studied. This QDM reached less than 1µT of background noise after 2 hours and 0.5µT of background noise after 8 hours. Finally, the magnetic field of a solenoid was successfully measured as a demonstration of the QDM.
