ABSTRACT
We describe a new method for imaging magnetic fields with 1000 Ã… resolution. The technique is based on using a force microscope to measure the magnetic force between a magnetized tip and the scanned surface. The method shows promise for the high-resolution mapping of both static and dynamic magnetic fields.

    Magnetic resonance (MR) images are normally corrupted by Rician noise which may mask the fine details in the image and decreases its resolution. This makes the feature extraction complicated which results in unreliable data analysis. Therefore denoising methods have been applied to improve the...

    Neutrons are highly sensitive to magnetic fields owing to their magnetic moment, whereas their charge neutrality enables them to penetrate even massive samples. The combination of these properties with radiographic and tomographic imaging enables a technique that is unique for investigations of...
