Abstract

A visualization method of magnetic flux density distribution using CT (computed tomography) technique is presented. In this method, the sensor (CT probe) is composed of only the coil pattern plane, and can visualize two-dimensional distribution of magnetic flux density of vertical component in the plane. If the sensor is composed as a multilayered CT probe, it is also possible to image the magnetic flux density distribution without physical scanning motion. To perform high sensitivity measurement, we propose a new shape of coil pattern with switch mechanism. We perform visualization of one frequency component of magnetic flux density distribution from a mixed frequency magnetic field
