Transfer of Graphene under Ultra-High Vacuum
This thesis reports on a novel method for graphene transfer that is fully UHV compatible, which has remained a challenge for a long time due to the necessity of supporting graphene for transfer and most often requiring supporting layer removal post-transfe ...
EPFL2022Analysis system and method for analysing the movement of a portion of the body and/or of a human prosthesis
Silvestro Micera, Andrea Crema, Fiorenzo Artoni
An analysis method (200) for analysing the pressure exerted by a portion of the body and/or of a human prosthesis comprises the following steps: sampling data generated by the portion of the body and/or the human prosthesis during a threshold calibration p ...
2021Level-line moirés by superposition of cylindrical microlens gratings
Jürgen Brugger, Roger Hersch, Thomas Walger, Valentin Flauraud, Théophane Besson
Two superposed layers of transparent cylindrical lenslet gratings create classical moiré fringes when illuminated from behind. We rely on this observation to conceive special devices made of superposed lenslet gratings that produce compelling beating shape ...
2020Moiré effects produced by superpositions of micro-lens arrays
Moiré effects result from the superimposition of repetitive structures. The beauty of these moirés comes from the fact that macroscopic shapes seem to appear from the superposition of layers containing microscopic patterns. In addition, the moirés are dyna ...
EPFL2020Holographic reconstruction of interlayer distance of bilayer two-dimensional crystal samples from their convergent beam electron diffraction patterns
Convergent beam electron diffraction (CBED) patterns of twisted bilayer samples exhibit interference patterns in their CBED spots. Such interference patterns can be treated as off-axis holograms and the phase of the scattered waves, and hence the interlaye ...
2020Near-field phase profile and far-field contrast modulation for micro-lens arrays at the refraction limit
Toralf Scharf, Maryam Yousefi, Daniel Necesal
We investigate the far-field pattern generation for a micro-lens array (MLA) illuminated under different conditions. Plane wave and Gaussian beam illumination are considered for an MLA with a small diameter of 27 microns and 30 microns period. At these dim ...
SPRINGER INTERNATIONAL PUBLISHING AG2020Accelerated MP2RAGE imaging using Cartesian phyllotaxis readout and compressed sensing reconstruction
Jean-Philippe Thiran, Tobias Kober, Tom Hilbert, Reto Meuli
Purpose MP2RAGE T-1-weighted imaging has been shown to be beneficial for various applications, mainly because of its good grey-white matter contrast, its B-1-robustness and ability to derive T(1)maps. Even using parallel imaging, the method requires long a ...
