Abstract: We demonstrated optical imagings of AC magnetic fields. A digital micro-mirror device and a lock-in detection allowed obtaining sub-millimeter resolution images without using magnetic shields. Images of gradient field from a wire suggested its potential to apply for signal-source estimations.
