Magnetic induction tomography using an all-optical $^{87}$Rb atomic magnetometer

摘要

We demonstrate Magnetic Induction Tomography (MIT) with an all-optical atomicmagnetometer. Our instrument creates a conductivity map of conductive objects.Both shape and size of the imaged samples compare very well with the actualshape and size. Given the potential of all-optical atomic magnetometers forminiaturization and extreme sensitivity, the proof-of-principle presented hereopens up promising avenues in the development of instrumentation for magneticinduction tomography.
