SIMULTANEOUS VECTOR MAGNETOMETRY WITH NITROGEN VACANCY CENTERS IN DIAMOND OR OTHER SOLID-STATE SPIN SENSORS

摘要

A system and method for performing vector magnetometry are described. A method can include illuminating diamond with a modulated optical signal and a modulated microwave (MW) signal. A first, bias magnetic field is also applied to the diamond. Light emitted from the diamond in response to the optical signal, the MW signal, and the first magnetic field is detected via a single detector at a fixed position relative to the diamond. A modulation of the detected light encodes information corresponding to a plurality of nitrogen vacancy (NV) axes of the diamond.
