Abstract

Visualizing an AC magnetic field distribution is valuable to evaluate spatially as signal or noise components and to estimate locations of signal sources. We propose an optical imaging technique to visualize AC magnetic field distributions. An atomic magnetometer with phase sensitive detections realize optical detections of the AC field with dividing into two axes. A digital micro-mirror device enables us to obtain the field image in 10 mm square area with sub-mm spatial resolution. As a result, bi-directional AC-field images from a fine metal-wire were obtained. The obtained images allow us to evaluate field distributions clearly. This imaging technique has a potential for spatial evaluations of AC field from electrical and electronic devices.
