Gradient-Based Correction of Chromatic Aberration in the Joint Acquisition of Color and Near-Infrared Images

Sabine Süsstrunk, Yue Lu, Zahra Sadeghipoor Kermani

Chromatic aberration distortions, such as wavelength-dependent blur caused by imperfections in photographic lenses, have long been studied in color imaging. The problem becomes more challenging to solve in the case of color and near-infrared joint acquisit ...

A Planar Feed for SOTM Ka-band Lens Antennas

Juan Ramon Mosig, Marc Esquius Morote, Maria Garcia Vigueras, Joana Rita Alves dos Santos Silva

Ka-band satellite technology has been drawing growing interest from public transportation industry to military applications, due to its advantages of higher speed links, smaller terminals and reduced costs. These well-recognized characteristics have also b ...

Motor-Primed Visual Attention for Humanoid Robots

Aude Billard, José Santos-Victor, Luka Lukic

We present a novel, biologically inspired, approach to an efficient allocation of visual resources for humanoid robots in a form of a motor-primed visual attentional landscape. The attentional landscape is a more general, dynamic and a more complex concept ...

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 ...

Origin and nature of measurement bias in catadioptric parallel goniophotometers

Marilyne Andersen, Boris Clément Karamata

We briefly categorize and compare parallel goniophotometers, which are instruments capable of simultaneously measuring the far-field distribution of light scattered by a surface or emitted by a source over a large solid angle. Little is known about the acc ...

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 ...

Live-cell multiplane three-dimensional super-resolution optical fluctuation imaging

Theo Lasser, Françoise Gisou van der Goot Grunberg, Marcel Leutenegger, Noelia Laura Bocchio, Aurélien Godinat, Patrick Alain Sandoz, Azat Sharipov

Super-resolution optical fluctuation imaging (SOFI) provides an elegant way of overcoming the diffraction limit in all three spatial dimensions by computing higher-order cumulants of image sequences of blinking fluorophores acquired with a classical widefi ...

Optical reconstruction of transparent objects with phase-only SLMs

Christian Depeursinge

Three approaches for visualization of transparent micro-objects from holographic data using phase-only SLMs are described. The objects are silicon micro-lenses captured in the near infrared by means of digital holographic microscopy and a simulated weakly ...

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 ...
