  • Patent number: 10408894
    Abstract: A method and device for determining values of a magnetic field component of a magnetic vector field. A method for determining values of a magnetic field component of a magnetic vector field, comprising: determining first distribution data comprising values of the magnetic field component, for a first predetermined area defined along a predetermined surface; determining second distribution data comprising second values of the component of the magnetic field for a second predetermined area defined along a second predetermined surface, wherein the first and the second predetermined surfaces are parallel; wherein determining second distribution data comprises manipulation of the first distribution data based on making use of intrinsic physical properties of the magnetic field; and associated device.

  • Patent number: 10310029
    Abstract: A method for determining a magnetic field of a magnet along a surface of the magnet, the method comprising: performing a relative movement between the surface of the magnet and a magnetic camera device; measuring the magnetic field by means of the magnetic camera device, to thereby obtain magnetic field measurements for the surface; wherein the relative movement is a continuous movement which is a combination of a relative translational movement and a relative rotational movement; and apparatus.

  • Patent number: 10241159
    Abstract: A method for determining a magnetic vector field in a predetermined area, the method comprising: determining distribution data comprising values of a first of three components of a magnetic field along a first direction, for a predetermined area defined on a predetermined surface, the predetermined surface being defined by a second and a third direction, wherein the first, second and third directions constitute an orthogonal set of axes; determining distribution data comprising values of the second and the third component of the magnetic field in the second and the third direction respectively, for the predetermined area defined in the predetermined surface; wherein determining distribution data comprising values of the second and the third component is based on making use of intrinsic physical relations between the first, second and third components of the magnetic field distribution; and associated device.

  • Patent number: 9797964
    Abstract: Embodiments described herein relate to devices and methods for determining a magnetic field distribution of a magnet along a main surface of said magnet. An example device for determining a magnetic field distribution of a magnet along a main surface of said magnet includes an arrangement of at least two independent magnetic field camera modules being arranged in a fixed relative position with respect to each other, each magnetic field camera module being adapted for measuring a magnetic field distribution to which it is exposed by means of a respective detection surface. The device also includes a means for providing a predetermined relative movement between the main surface and the arrangement to thereby scan the magnetic field distribution of the magnet along the main surface.

  • Patent number: 7902820
    Abstract: Certain inventive aspects provide local field imaging with high spatial, time and field resolution by using an array of Hall effect sensors that can be individually read out. The design combines semiconductor Hall sensors and switches that isolate the addressed Hall sensor from the rest of the array. The compact design allows for large and very dense Hall sensor arrays that can be read out in a straightforward way.
