Hemispherical Multiple Camera System for High Resolution Omni-Directional Light Field Imaging

Yusuf Leblebici, Alexandre Schmid, Hossein Afshari, Kerem Seyid, Abdulkadir Akin, Ömer Cogal

Inspiration from light field imaging concepts has led to the construction of multi-aperture imaging systems. Using multiple cameras as individual apertures is a topic of high relevance in the light field imaging domain. The need for wide field-of-view (FOV ...

Optical-resolution photoacoustic microscopy by use of a multimode fiber

Demetri Psaltis, Christophe Moser, Salma Farahi

We demonstrate Optical-Resolution Photoacoustic Microscopy (OR-PAM), where the optical field is focused and scanned using Digital Phase Conjugation through a multimode fiber. The focus is scanned across the field of view using digital means, and the acoust ...

Resonant PZT MEMS Scanner for High-Resolution Displays

Paul Muralt, Davide Balma

A resonant piezoelectric scanner is developed for high-resolution laser-scanning displays. A novel actuation scheme combines the principle of mechanical amplification with lead zirconate titanate (PZT) thin-film actuation. Sinusoidal actuation with 24 V at ...

Micro-beamer based on MEMS micro-mirrors and laser light source

Maher Kayal, Laurent Fabre, Nicolas Abelé, Christophe Winter, Fabrizio Lo Conte

This paper presents a complete portable laser-based projection system using two one-dimensional magnetic actuated MEMS linear scanning micro-mirrors. Dedicated high speed electronics was developed to drive the MEMS, detect the mirror scanning position at a ...

Method for spatially scalable video coding

Pierre Vandergheynst

A method for decomposing a digital image at resolution R and MR into a set of spatial sub-bands of resolution R and MR where MR>R and where the high-band at resolution MR is calculated by subtracting the filtered and up-sampled image at resolution R from t ...

Towards improving the simulation of meteorological fields in urban areas through updated/advanced surface fluxes description

Alain Clappier

The increased resolution of numerical weather prediction models allows nowadays addressing more realistically urban meteorology and air pollution processes. This has triggered new interest in modelling and describing experimentally the specific features an ...
