| Sumario: | Abstract Spectroscopic analysis of AC magnetic signal using diamond quantum magnetometry is a promising technique for inductive imaging. Conventional dynamic decoupling like XY8 provides a high sensitivity of an oscillating magnetic signal with intricate dependence on magnitude and phase, complicating high throughput detection of each parameter. In this study, a simple measurement scheme for independent and simultaneous detection of magnitude and phase is demonstrated by a sequential measurement protocol. Wide-field imaging experiment was performed for an oscillating magnetic field with approximately $$100\,\upmu \hbox {m}$$ 100μm -squared observation area. Single pixel phase precision was $$2.1^{\circ }$$ 2.1∘ for $$0.76\,\upmu \hbox {T}$$ 0.76μT AC magnetic signal. Our method enables potential applications including inductive inspection and impedance imaging. |
