Abstract
The sensitive detection of either static or radio-frequency \textsc{(rf)} magnetic fields is essential to many fundamental studies and applications. Here, we demonstrate the operation of a cold-atom-based, \textsc{rf} magnetometer in performing {1-D and 2-D imaging} of small metallic objects. It is based on a cold Rb atomic sample, and operates in an unshielded environment with no active field stabilization. It shows a sensitivity up to in the range bandwidth and can resolve a cut wide in a thick metallic foil. The characteristics of our system make it a good candidate for applications in civil and industrial surveillance.
