Single-Photon Synchronous Detection

Edoardo Charbon, Ties Jan Henderikus Kluter, Cristiano Niclass, Claudio Favi, Frédéric Monnier

A novel imaging technique is proposed for fully digital detection of phase and intensity of light. A fully integrated camera implementing the new technique was fabricated in a 0.35μm CMOS technology. When coupled to a modulated light source, the camera can ...

Modeling the surface charge evolution of spherical nanoparticles by considering dielectric discontinuity effects at the solid/electrolyte solution interface

Marianne Seijo, Montserrat Filella, Serge Stoll

It is well known that the electrostatic repulsions between charges on neighboring sites decrease the effective charge at the surface of a charged nanoparticle (NP). However, the situation is more complex close to a dielec. discontinuity, since charged site ...

High Speed CMOS Imaging: Four Years Later

Edoardo Charbon

Four years ago [1] we assessed the status of CMOS imaging for high-speed applications. We also gave an outlook of the near future in high-speed imaging In this paper we revisit the topic of high speed imaging in a slightly different angle and make the poin ...

On Benchmarking Camera Calibration and Multi-View Stereo for High Resolution Imagery

Pascal Fua, Christoph Strecha

In this paper we want to start the discussion on whether image based 3-D modelling techniques can possibly be used to replace LIDAR systems for outdoor 3D data acquisition. Two main issues have to be addressed in this context: (i) camera calibration (inter ...

Fast Bias Field Correction for 9.4 Tesla Magnetic Resonance Imaging

Jean-Philippe Thiran, Rolf Gruetter, Meritxell Bach Cuadra, Nicolas Kunz, Nathalie Just, Xavier Pena Pina

In this paper the problem of intensity inhomogeneity at high magnetic field on magnetic resonance images is addressed. Specifically, rat brain images at 9.4T acquired with a surface coil are bias corrected. We propose a low- pass frequency model that takes ...

Semiconductor Image Sensing

Peter Seitz, Nicolas Blanc

Silicon is an excellent detector material for electromagnetic radiation in the wavelength range of 0.1 to 1000 nm. In the visible spectral range (400-700 nm), external quantum efficiencies approaching 100% are obtained. When combined with the amazing minia ...

Acquisition et recalage informatique d'images confocales de tissus denses

Nicolas Fête

Analysis of the 3D structure of a biological sample is an important step to model cell and tissue dynamics. As a model system, we set up to determine the number of nuclei in a follicular papilla using confocal imaging and 3D computer reconstruction. The fo ...
