Application of Adaptive Optics to Focusing and Imaging

Daniel Iwaniuk

Adaptive optics is used to abate aberrations with a wavefront correction. It is widely used in astronomy and is starting to expand into applications of laser focusing and imaging with high numerical apertures, e.g. microscopy. The physical background of fo ...

Microcamera aperture scale in monocentric gigapixel cameras

Multiscale cameras achieve wide-angle, high-resolution imaging by combining coarse image formation by a simplified wide-field objective with localized aberration correction in an array of narrow field microcameras. Microcamera aperture size is a critical p ...

Microlenses with defined contour shapes

Jürgen Brugger, Victor Javier Cadarso Busto, Loïc Jacot-Descombes

Ink-jet printing of optical ink over SU-8 pillars is here proposed as a technology for obtaining microlenses with shape control. To demonstrate the flexibility of this method, microlenses with five different contour shapes (ranging from circular and ellipt ...

Coherent transfer functions and extended depth of field

Theo Lasser, Christophe Pache, Rainer Leitgeb, Martin Villiger

To preserve the speed advantage of Fourier Domain detection in Optical Coherence Microscopy (OCM), extended depth of field is needed. With a narrow probing volume that extends over a long axial range, tissue could be measured in vivo and at cellular resolu ...

Extended Focus Optical Coherence Microscopy

Martin Villiger

Optical coherence tomography (OCT) is an interferometric imaging technique that can provide depth resolved cross-sectional views of biological tissue. OCT employs light with low temporal and yet high spatial coherence. The sample is illuminated point by po ...

Seeing the body modulates audiotactile integration

Olaf Blanke, Jane Aspell, Bigna Lenggenhager

Audiotactile integration has been studied using various experimental setups but so far crossmodal congruency effects (CCEs) have not been found for tactile targets paired with auditory distractors. In the present study we investigated whether audiotactile ...

Small-size microlens characterization by multiwavelength high-resolution interference microscopy

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

Microlenses are widely studied in two main areas: fabrication and characterization. Nowadays, characterization draws more attention because it is difficult to apply test techniques to microlenses that are used for conventional optical systems. Especially, ...

Spatio-temporally focused femtosecond laser pulses for nonreciprocal writing in optically transparent materials

Yves Bellouard, Erica Kathleen Block

Simultaneous spatial and temporal focusing (SSTF) provides precise control of the pulse front tilt (PFT) necessary to achieve nonreciprocal writing in glass wherein the material modification depends on the sample scanning direction with respect to the PFT. ...

Visual capture and the experience of having two bodies

Olaf Blanke, Jane Aspell, Lukas Heydrich

The experience of singularity of the conscious self may break down in heautoscopy. In heautoscopy patients see a double or doppelganger of themselves. Moreover, the self may be experienced as reduplicated—existing at two or even more locations simultaneous ...

A virtual 3D mobile guide in the INTERMEDIA project

Daniel Thalmann, Xavier Righetti, Achille Peternier

In this paper, we introduce a European research project, interactive media with personal networked devices (INTERMEDIA) in which we seek to progress beyond home and device-centric convergence toward truly user-centric convergence of multimedia. Our vision ...
