A real time high sensitivity high spatial resolution quantum well hall effect magnetovision camera

•Develop a real time magnetovision camera for fast scanning speed requirement of NDT.•The system provide 2D graphical imaging, similar to MPI, but without its inherent drawbacks.•Provide 2D images for configuration identification of materials similar to X-ray.•The system can use in multiple sampling measurements to give better signal to noise ratios.•Offer many advantages such as high linearly, sensitivity and spatial resolution.
