Magnetic induction tomography using an all-optical ⁸⁷Rb atomic magnetometer

Opt Lett. 2014 Nov 15;39(22):6367-70. doi: 10.1364/OL.39.006367.

Abstract

We demonstrate magnetic induction tomography (MIT) with an all-optical atomic magnetometer. Our instrument creates a conductivity map of conductive objects. Both the shape and size of the imaged samples compare very well with the actual shape and size. Given the potential of all-optical atomic magnetometers for miniaturization and extreme sensitivity, the proof-of-principle presented in this Letter opens up promising avenues in the development of instrumentation for MIT.
