Electromagnetic Imaging with Atomic Magnetometers: A Novel Approach to Security and Surveillance (1605.01914v1)
Published 6 May 2016 in physics.atom-ph and physics.ins-det
Abstract: We describe our research programme on the use of atomic magnetometers to detect conductive objects via electromagnetic induction. The extreme sensitivity of atomic magnetometers at low frequencies, up to seven orders of magnitude higher than a coil-based system, permits deep penetration through different media and barriers, and in various operative environments. This eliminates the limitations usually associated with electromagnetic detection.
