Abstract

Spatial distribution measurement of AC magnetic field is valuable to estimate locations of signal sources. Optical measurement of magnetic field is a low-invasive method and has potentials to expand magnetic field imaging applications. We propose optical measurement and imaging of AC magnetic field by combining a digital micro-mirror device and an optical magnetometer. The conventional scanning-based imaging causes the lack of light intensity for the higher spatial resolution. Hadamard transformation imaging technique resolve the intensity issue and realize higher spatial resolution imaging. This imaging technique has a possibility for precise evaluation of AC field distributions from electrical and electronic devices.
