Electromagnetic induction imaging with a scanning radio frequency atomic magnetometer

We demonstrate electromagnetic induction imaging with an unshielded, portable radio frequency atomic magnetometer scanning over the target object. This configuration satisfies standard requirements in typical applications, from security screening to medical imaging. The ability scan object relies on miniaturization of sensor head, active compensation ambient magnetic field, and implementation a dedicated procedure extract high-quality images recorded spatial dependent resonance. is shown be effective suppressing detrimental effects variation environment.
