| Outline of Final Research Achievements |
We utilized an optical magnetometer to detect AC magnetic field. At first, small permanent magnets were used instead of big coils to generate static magnetic field around the sensor head. Non-uniform magnetic field from permanent magnets produced reduction of output signals and a higher bandwidth.
Subsequently, we achieved to visualize magnetic field distributions with sub-millimeter resolutions by using a mirror array device. Uniform field distributions from Helmholtz coils and field decays from a fine wire were clearly obtained.
