Multiple-Field Approach for Aberration Correction in Miniature Imaging Systems Based on Wafer-Level Production

Hans Peter Herzig, Toralf Scharf, Nicolas Bongard

IIn mobile imaging systems, the most difficult element to integrate is the objective lens. Here we present an intermediate approach between the costly traditional objectives and the low-resolution objectives inspired by the compound eyes of insects. Our mu ...

Curved Transflective Holographic Screens for Head-Mounted Display

Jürgen Brugger, Christophe Moser, Eric Tremblay, Victor Javier Cadarso Busto, Jonas Grossenbacher, Arnaud Mader, Seyedpayam Vahdati

A volume hologram recorded with a lens array is proposed as a transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a projection system, with similar properties to one mounted on ...

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 ...

Generation of highly confined optical bottle beams by exploiting the photonic nanojet effect

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report on the generation of photonic nanojets, which resemble optical bottle beams. They are realized by manipulating the illumination of dielectric microspheres. As illumination we use the outer region of deliberately truncated Bessel-Gauss beam or a f ...

Seeing your error alters my pointing: observing systematic pointing errors induces sensori-motor after-effects

Roberta Ronchi

During the procedure of prism adaptation, subjects execute pointing movements to visual targets under a lateral optical displacement: as consequence of the discrepancy between visual and proprioceptive inputs, their visuo-motor activity is characterized by ...

On the evolution of environmental and mass properties of strong lens galaxies in COSMOS

Jean-Paul Richard Kneib

Context. Nearly 100 new strong-lens candidates have been discovered in the COSMOS field. Among these, 20 lens candidates with 0.34 less than or similar to z(lens)

New inks for the direct drop-on-demand fabrication of polymer lenses

Jürgen Brugger, Vahid Fakhfouri, Joo Yeon Kim

The advent of cell phone cameras extensively pushed market needs for micro lenses and supported developments like the Wafer-Level-Camera Technology [1]. Different optical applications and patterning methods for micro lenses require different sets of materi ...

Correcting spherical aberrations induced by an unknown medium through determination of its refractive index and thickness

Pramod Rastogi, Daniel Iwaniuk

In imaging and focusing applications, spherical aberration induces axial broadening of the point spread function (PSF). A transparent medium between lens and object of interest induces spherical aberration. We propose a method that first obtains both the p ...

Towards a model for View Direction patterns as a function of light distribution

Mandana Sarey Khanie

DAYLIGHT is a desirable architectural component that satisfies both visual and psychological needs of the occupants. Therefore it is essential to integrate this component in the design in a way that maximum daylight is guaranteed and a visually healthy and ...

A generalized-gradient approximation exchange hole model for dispersion coefficients

A simple method for computing accurate density-dependent dispersion coefficients is presented. The dispersion coefficients are modeled by a generalized gradient-type approximation to Becke and Johnson's exchange hole dipole moment formalism. Our most cost- ...
