Magnetometers have a wide range of utilization from Nuclear Magnetic Resonance (NMR), to medical applications such as the Magneto-Encephalogram (MEG), Magnetocardiography (MCG), and Magnetic Resonance Imaging (MRI). However, these techniques often depend on superconducting quantum interference detection magnetometers or the detection of a radio frequency magnetic resonance in a paramagnetic target induced while in a large field. Chip-scale, low-power optical magnetometers can improve the cost and size as well as reduce the complexity of these devices. The directional variation of sensitivity of these detectors can be exploited to make devices that can form images. We have designed and instrument that will be the functional equivalent of a portable MRI that will be capable of near real-time imaging. The inverse algorithm of mapping a series of detector responses to a magnetic “image” has been calculated and an algorithm for rapidly calculating images from sparse optical magnetometer data sets has been developed. Experimental measurement of the directional sensitivity of Rb-based optical magnetometers will be presented. A prototype imaging system for magnetic tomography is being constructed.
