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.
