Curved Holographic Combiner for Color Head Worn Display

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

A volume hologram recorded with a lens array is proposed as a color transflective screen for Head Worn Display (HWD) systems. Design, fabrication as well as proof of concept are reported. Light from a single MEMS-based projector is efficiently diffracted t ...

On-chip near-infrared optical spectrometer based on single-mode Epo waveguide and gold nanoantennas

Toralf Scharf, Irène Antoinette Philipoussis, Joab Di Francesco

We report about optical spectrometry using gold nanostructures printed on top of an integrated optical waveguide. The optical waveguide is a single-mode buried waveguide made from a combination of photo-polymerizable materials and is fabricated by photolit ...

Real-time 3D particle manipulation visualized using volume holographic gratings

Yves Chevallier

Holographic optical tweezers (HOTs) extend optical trapping into three dimensions. Volume imaging then becomes a concern as trapped objects are easily moved out of focus of the imaging objective lens. Here we demonstrate a three-dimensional real-time inter ...

A Practical Method for Measuring the Spatial Frequency Response of Light Field Cameras

Sabine Süsstrunk, Loïc Arnaud Baboulaz, Damien Firmenich

The spatial frequency response (SFR) is one of the most important and unbiased image quality measures of a digital camera. It evaluates to which extent a lens/sensor combination can resolve scene details. In this paper, we propose a simple and practical me ...

A 7 deg(2) survey for galaxy-scale gravitational lenses with the HST imaging archive(star)

Frédéric Courbin, Georges Meylan

We present the results of a visual search for galaxy-scale gravitational lenses in similar to 7 deg(2) of Hubble Space Telescope (HST) images. The data set comprises the whole imaging data ever taken with the Advanced Camera for Surveys (ACS) in the filter ...

Experimental and theoretical investigation on the misalignment tolerance of a micron-sized solid immersion lens tolerance of a micron-sized solid immersion lens

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim

We report an experimental and theoretical study on the alignment error tolerance of a 2 µm-size solid immersion lens (SIL) illuminated by different types of focused spots. Tightly confined focal spots are of great interest for improving the performance of ...

Curved Transflective Holographic Screens for Head-Mounted Display

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

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 ...

Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique

Edoardo Charbon, Jürgen Brugger, Dmitri Boiko, Vahid Fakhfouri, Joo Yeon Kim, Nils Benedict Brauer

Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. Using this simple technique, we de ...

Full-field microimaging with 8 keV X-rays achieves a spatial resolutions better than 20 nm

Giorgio Margaritondo

Fresnel zone plates (450 nm thick Au, 25 nm outermost zone width) used as objective lenses in a full field transmission reached a spatial resolution better than 20 nm and 1.5% efficiency with 8 keV photons. Zernike phase contrast was also realized without ...
