Overcoming the resolution limit in retinal imaging using the scattering properties of the sclera

Demetri Psaltis, Christophe Moser, Timothé Laforest, Dino Carpentras

In-vivo imaging of the eye's fundus is widely used to study eye's health. State of the art Adaptive Optics devices can resolve features up to a lateral resolution of 1.5 um. This resolution is still above what is needed to observe subcellular structures su ...

High-contrast self-imaging with ordered optical elements

Hans Peter Herzig, Ali Naqavi, Mattia Rossi

Creating arbitrary light patterns has applications in various domains, including lithography, beam shaping, metrology, sensing, and imaging. We study the formation of high-contrast light patterns obtained by transmission through an ordered optical element ...

Predictability, efference copies, and non-retinotopic motion

Michael Herzog, Marc Michael Lauffs

Perception is usually non-retinotopic. For example, visual perception is stable even though the retinal image is constantly changing due to eye and body movements. Likewise, a reflector on the wheel of a bicycle is perceived to rotate on a circular orbit, ...

Elucidating the role of Hmx1 during mouse development

Linda Bapst

This thesis focuses on the study of H6 homeobox 1 (HMX1) gene, a homeobox-containing transcription factor involved in sensory organ and eye development and responsible for the oculo-auricular syndrome of Schorderet-Munier-Franceschetti. The purpose of my s ...

EPFL2015

Contrast sensitivity of the human visual system to visual stimuli can be significantly affected by several mechanisms, e. g., vision foveation and attention. Existing studies on foveation based video quality assessment only take into account static foveati ...

A Dimerized HMX1 Inhibits EPHA6/epha4b in Mouse and Zebrafish Retinas

HMX1 is a homeobox-containing transcription factor implicated in eye development and responsible for the oculo-auricular syndrome of Schorderet-Munier-Franceschetti. HMX1 is composed of two exons with three conserved domains in exon 2, a homeobox and two d ...

Retinal and post-retinal contributions to the quantum efficiency of the human eye revealed by electrical neuroimaging

Enrico Pomarico, Nicolas Gisin

The retina is one of the best known quantum detectors with rods able to reliably respond to single photons. However, estimates on the number of photons eliciting conscious perception, based on signal detection theory, are systematically above these values ...

Binocular suppression occurs in object-centered coordinates

Michael Herzog, Marco Boi, Marcus Leonardus Vergeer

In binocular rivalry, only one image is perceived consciously when different, incompatible images are presented to the left and right eye, respectively. The other image is suppressed. Binocular suppression is generally assumed to occur within retinotopic c ...

Contrast Enhancement in Optical Coherence Microscopy

Christophe Pache

Optical Coherence Microscopy (OCM) is a three-dimensional imaging technique that provides cross-sectional views of the subsurface microstructure of biological tissue, with a high axial and lateral resolution. In OCM, a low time coherence light source is sp ...

In vivo assessment of myelination by phase imaging at high magnetic field

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

The present study evaluated the potential of using the phase of T-2* weighted MR images to characterize myelination during brain development and pathology in rodents at 9.4 T. Phase contrast correlated with myelin content assessed by histology and suggests ...
