On Stochastic Processes Driven by Ballistic Noise Sources

Max-Olivier Hongler, Roger Filliger, Philippe Blanchard, Julio Rodriguez

Among the rich collection of noise sources that can be used to drive stochastic differential equations (SDE), we here focus on Markov processes that themselves are functions of the standard Brownian motion and of the Telegrapher’s process. Our present nois ...

Comparison of Two Cameras based on Single Photon Avalanche Diodes (SPADs) for Fluorescence Lifetime Imaging Application with Picosecond Resolution

Edoardo Charbon, Claudio Bruschini, Francesco Regazzoni, Samuel Burri, François Eric Powolny

We report on a comparative study of two time-resolved cameras based on digital Single Photon Avalanche Diodes (SPADs) for Fluorescen ce Lifetime Imaging applications. In contrast to standard imagers such as cameras, SPAD imagers provide intensity as well a ...

Electronics for the camera of the First G-APD Cherenkov Telescope (FACT) for ground based gamma-ray astronomy

Werner Lustermann, Mathieu Ribordy, Thomas Günther Bretz

Within the FACT project, we construct a new type of camera based on Geiger-mode avalanche photodiodes (G-APDs). Compared to photomultipliers, G-APDs are more robust, need a lower operation voltage and have the potential of higher photon-detection efficienc ...

Quantitative Comparison of Commercial CCD and Custom-Designed CMOS Camera for Biological Applications

Giovanni De Micheli, Sandro Carrara, René Beuchat, Yusuf Leblebici, Gözen Köklü, Julien Michel Ghaye

In biological applications and systems where even the smallest details have a meaning, CCD cameras are mostly preferred and they hold most of the market share despite their high costs. In this paper, we propose a custom-designed CMOS camera to compete with ...

Low-Noise, High-Density Microelectronics for Multi-Mode Screening of Excitable Biological Cells

Urs Alexander Müller

In the past decades, two recording tools have established themselves as the working horses in the field of electrophysiological cell research: the microelectrode array (MEA) and the optical fluorescence imaging. The former is a grid of miniature electrodes ...

Signal fluctuations in fMRI data acquired with 2D-EPI and 3D-EPI at 7 Tesla

Wietske Van der Zwaag, José Pedro Rebelo Ferreira Marques, João Pedro Forjaco Jorge, Patricia Figueiredo

Segmented three-dimensional echo planar imaging (3D-EPI) provides higher image signal-to-noise ratio (SNR) than standard single-shot two-dimensional echo planar imaging (2D-EPI), but is more sensitive to physiological noise. The aim of this study was to co ...

On the damping of room resonances with electroacoustic absorbers in the low frequency range

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet, Iris Rigas

In closed spaces, standing waves occur at low frequencies, thus creating annoying acoustic resonances. Such unwanted phenomena are likely to affect the annoyance of noise sources in the low frequency range. Up to date, low-frwquency treatments are mainly b ...

Optimal operating points of oscillators using nonlinear resonators

Luis Guillermo Villanueva Torrijo

We demonstrate an analytical method for calculating the phase sensitivity of a class of oscillators whose phase does not affect the time evolution of the other dynamic variables. We show that such oscillators possess the possibility for complete phase nois ...

An Implementation of a Spike-Response Model with Escape Noise Using an Avalanche Diode

Edoardo Charbon

This paper introduces a novel probabilistic spike-response model through the combination of avalanche diode-generated Poisson distributed noise, and a standard exponential decay-based spike-response curve. The noise source, which is derived from a 0.35- m ...

Synchronous and Asynchronous Detection of Ultra-Low Light Levels

Peter Seitz, Christian Lotto

Comprehensive analysis of noise sources in photocharge detectors leads to two novel, compact pixel circuits for ultra-low-noise light detection using optimum bandwidth engineering. A synchronous 4T CMOS image sensor pixel with in-pixel amplification reache ...
