Effectiveness of X-ray micro-CT applications upon mafic and ultramafic ophiolitic rocks

Pascal Turberg

X-ray micro-computed tomography (mu CT) was applied upon selected ophiolitic rock samples from various localities of the Vardar ophiolite outcrops in North Greece. Effectiveness of the mu CT application was evaluated through this case study by comparing re ...

Magnetic force microscopy contrast formation and field sensitivity

Marcos Penedo Garcia, Johannes Schwenk

The magnetic force microscope (MFM) is an established experimental tool for imaging stray fields with high spatial resolution and sensitivity. The MFM contrast can however contain contributions from the sample topography, variations in the surface Kelvin p ...

Correcting spherical aberrations induced by an unknown medium through determination of its refractive index and thickness

Pramod Rastogi

In imaging and focusing applications, spherical aberration induces axial broadening of the point spread function (PSF). A transparent medium between lens and object of interest induces spherical aberration. We propose a method that first obtains both the p ...
