We demonstrate high-resolution magnetic field imaging with a scanning fiber-optic probe which couples nitrogen-vacancy (NV) centers in diamond to a high-numerical-aperture photonic-crystal fiber integrated with a two-wire microwave transmission line. Magnetic resonance excitation of NV centers driven by the microwave field is read out through optical interrogation through the photonic-crystal fiber to enable high-speed, high-sensitivity magnetic field imaging with sub 30 μm spatial resolution.
我们展示了一种利用扫描光纤探头进行高分辨率磁场成像的方法，该探头将金刚石中的氮空位（NV）中心与集成有双线微波传输线的高数值孔径光子晶体光纤相耦合。由微波场驱动的NV中心的磁共振激发通过光子晶体光纤进行光学探测来读出，从而实现具有亚30μm空间分辨率的高速、高灵敏度磁场成像。
