Outline of Final Research Achievements |
We suggested the novel methods inspired by MRI and CT to realize simultaneous mulitilocation measurements with an optically pumped atomic magnetometer (OPAM) toward biomagnetic-field measurements. For the MRI-like method, the pump beams of the OPAM was modulated to encode the signals. We successfully demonstrated simultaneous multilocation measurements by this technique. For the CT-like method, first of all, we fabricated a new multi-channel probe-beam detector at a reasonably low cost. This detector made us acquire 10 signals simultaneously. With this detector, we measured the magnetic-field distribution generated from a loop coil and successfully reconstructed the field map by the signal processing.
