论文摘要
使用钻石量子磁力测定法对AC磁信号进行光谱分析是一种有前途的电感成像技术。像XY8这样的常规动态解耦提供了振荡磁信号的高灵敏度，并具有复杂的幅度和相位，从而使每个参数的高吞吐量检测变得复杂。在这项研究中，通过顺序测量方案证明了一个简单的测量方案，用于独立和同时检测幅度和相位。对大约100 $ $ M平方观测区的振荡磁场进行了广场成像实验。单像素相位的精度为$ 2.1^\ circ $，对于0.76 $ $ $ t ac磁信号。我们的方法可实现潜在的应用，包括归纳检查和阻抗成像。
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$μ$m-squared observation area. Single pixel phase precision was $2.1^\circ$ for 0.76$μ$T AC magnetic signal. Our method enables potential applications including inductive inspection and impedance imaging.
