We use Faraday spectroscopy of atoms confined to crossed hollow beam tweezers to map magnetic fields over 3 millimeters with 200 micron resolution in a single trap loading cycle. The hollow beams are formed using spatial light modulation, and the trap location is scanned using acousto-optic deflectors. We demonstrate the technique by mapping a linear quadrupole magnetic field with 10 nT sensitivity.
我们使用限制在交叉空心光束镊子中的原子的法拉第光谱，在单个陷阱加载周期内以200微米的分辨率绘制超过3毫米范围的磁场图。空心光束通过空间光调制形成，陷阱位置使用声光偏转器进行扫描。我们通过绘制灵敏度为10 nT的线性四极磁场来演示该技术。
