WIENER FILTERING APPLIED TO MAGNETIC NEAR FIELD SCANNING

Magnetic Resonance Im Sequential anisotropic Wiener filtering applied to 3D MRI data

We present three different sequential Wiener filters, namely, isotropic, orientation and anisotropic. The first one is similar to the classical Wiener filter in the sense that it uses an isotropic neighborhood to estimate its parameters. Here we present a sequential version of it. The orientation Wiener filter uses oriented neighborhoods to estimate the structure orientation present at each vox...

Scanning near-field optical microscopy.

An average human eye can see details down to 0,07 mm in size. The ability to see smaller details of the matter is correlated with the development of the science and the comprehension of the nature. Today's science needs eyes for the nano-world. Examples are easily found in biology and medical sciences. There is a great need to determine shape, size, chemical composition, molecular structure and...

An overview of scanning near-field optical microscopy in characterization of nano-materials

Scanning Near-Field Optical Microscopy (SNOM) is a member of scanning probe microscopes (SPMs) family which enables nanostructure investigation of the surfaces on a wide range of materials. In fact, SNOM combines the SPM technology to the optical microscopy and in this way provide a powerful tool to study nano-structures with very high spatial resolution. In this paper, a qualified overview of ...
