HallinSight® vectorial magnetic field imaging technology, a true off-the-shelf 3D-Hall Magnetic Field Camera.
Making the invisible visible with true three-axis magnetic field cameras, HallinSight® systems map dynamic magnetic fields in real time. Arrays of 32×32, 16×16, or 32×2 3-axis Hall sensors measure from several μT up to a few T at rates of 25, 100, and 250 Hz, respectively. See the video below for a demonstration.
HallinSight® is a technology developed by Fraunhofer Institute for Integrated Circuits.
