Analytical ultracentrifugation to support the development of biomaterials and biomedical devices
Jeffrey Alan Hubbell, Jutta Christine Wandrey, Conlin O'Neil, Urara Hasegawa
Analytical ultracentrifugation (AUC) primarily serves to investigate hydrodynamic and thermodynamic properties of natural and synthetic macromolecules and colloids in solution, dispersion or suspension. Beside such more conventional use, AUC can support ma ...
2011Characterization of Nanoparticles Using Non-linear Correlation Spectroscopy
Theo Lasser, Marcel Leutenegger, Iwan Märki, Jean-Pierre Wolf, Noelia Laura Bocchio, Luigi Bonacina
Nanoparticles are interesting for biomedical imaging as novel non- fluorescent non-bleaching labels. We present the characterization of freely diffusing nanoparticles using third harmonic generation correlation spectroscopy by illumination with a focussed ...
2011Optomechanically Induced Transparency
Tobias Kippenberg, Albert Schliesser, Emanuel Gavartin, Stefan Alexander Weis
Electromagnetically induced transparency is a quantum interference effect observed in atoms and molecules, in which the optical response of an atomic medium is controlled by an electromagnetic field. We demonstrated a form of induced transparency enabled b ...
2010Registration for Super-Resolution: Theory, Algorithms, and Applications in Image and Mobile Video Enhancement
Martin Vetterli, Luciano Sbaiz, Patrick Vandewalle
The relation between sensor resolution and the optics of a digital camera is determined by the Nyquist sampling theorem: the sampling frequency should be larger than twice the maximum frequency of the image content coming out of the optical system. If a lo ...
Taylor& Francis / CRC Press2010Optical Imaging Using Binary Sensors
Michaël Unser, François Aguet, Aurélien Bourquard
This paper addresses the problem of reconstructing an image from 1-bit-quantized measurements, considering a simple but nonconventional optical acquisition model. Following a compressed-sensing design, a known pseudo-random phase-shifting mask is introduce ...
OSA2010Measurement of the coherent transfer function
Theo Lasser, Christophe Pache, Martin Villiger
It is important to characterize and quantify the imaging performance of optical coherence tomography (OCT) and especially optical coherence microscopy (OCM) systems for validation and calibration of the setup. We suggest using a simple rubber surface, pres ...
2010Advanced passive micro-optical elements
Micro-optical elements are optical elements having size or details in the range of the micrometer scale. The emergency of such elements is strongly linked to the development made in the fabrication techniques during the nineties to follow the still actual ...
