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…
Magnetic Lenz lenses increase the limit-of-detection in nuclear magnetic resonance
Nils Spengler, Peter T. While, Markus V. Meissner +2
A high NMR detection sensitivity is indispensable when dealing with mass and volume-limited samples, or whenever a high spatial resolution is required. The use of miniaturised RF c…
Topological in-plane polarized piezo actuation for compact adaptive lenses with aspherical correction
Florian Lemke, Moritz Stürmer, Ulrike Wallrabe +1
In this contribution, we investigate the effects of using in-plane polarized piezo actuators with topological buckling displacement to drive glass-piezo composite membranes for ada…
Single-Sided Contacting of Out-of-Plane Polarized Piezo Films for Fluid Membrane Lenses
Moritz Stürmer, Matthias C. Wapler, Ulrike Wallrabe
We present an adaptive lens which tunes its focal length with a glass membrane that is deformed by an integrated piezo bending actuator. A particular challenge in the fabrication o…
