Inhalt:
We report on a three-axis magnetic field camera system, capable of measuring the three components of the magnetic field distribution in a two-dimensional plane with high spatial resolution and at high speed. This new development, which is also commercially available, is illustrated by performing a full inspection of a rotary sensor magnet, whereby we inspect the complete vector magnetic field distribution, including the Bx, By and Bz components, as well as derived magnetic field components such as the full B-field and the distribution of the magnetic field vector direction (polar and azimuthal angles). Applications are found in R&D, production and quality control environments in different industries, such as sensor systems, permanent magnet motors, medical devices, automotive engineering, magnet manufacturing, consumer electronics and research institutes, where it can contribute to speed up R&D cycles, reduce time-to-market, quickly identify magnet quality issues and assure high quality products and high yield levels in the production line.
