Depth-controlled Bessel beams
Angelina Müller, Matthias C. Wapler, Ulrike Wallrabe
We present a ring aperture with independently switchable segments for the three-dimensional control of quasi propagation invariant beams. We demonstrate that our liquid crystal des…
A compact, large-aperture tunable lens with adaptive spherical correction
Matthias C. Wapler, Moritz Stürmer, Ulrike Wallrabe
In this paper, we present the proof of concept of a very fast adaptive glass membrane lens with a large aperture/diameter ratio, spherical aberration correction and integrated actu…
Magnetic properties of materials for MR engineering, micro-MR and beyond
Matthias C Wapler, Jochen Leupold, Iulius Dragonu +3
We present the results of a systematic measurement of the magnetic susceptibility of small material samples in a 9.4 T MRI scanner. We measured many of the most widely used materia…
