High-dynamic-range imaging with photon-counting arrays (Conference Presentation)
Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic
We present a comprehensive analysis to guide the use of the nonlinear photon response in photon-counting arrays to extend their optical dynamic range far beyond 1/Tdead, where Tdead is the pixel dead time after photon detection, so as to achieve a high dyn ...
2019Modeling and Analysis of a Direct Time-of-Flight Sensor Architecture for LiDAR Applications
Edoardo Charbon, Chunmin Zhang, Preethi Padmanabhan
Direct time-of-flight (DTOF) is a prominent depth sensing method in light detection and ranging (LiDAR) applications. Single-photon avalanche diode (SPAD) arrays integrated in DTOF sensors have demonstrated excellent ranging and 3D imaging capabilities, ma ...
2019Slasher: Stadium racer car for event camera end-to-end learning autonomous driving experiments
Slasher is the first open 1/10 scale autonomous driving platform for exploring the use of neuromorphic event cameras for fast driving in unstructured indoor and outdoor environments. Slasher features a DAVIS event-based camera and ROS computer for percepti ...
2019Dynamic range extension for photon counting arrays
Edoardo Charbon, Claudio Bruschini, Ivan Michel Antolovic
Confocal microscopes use photomultiplier tubes and hybrid detectors due to their large dynamic range, which typically exceeds the one of single-photon avalanche diodes (SPADs). The latter, due to their photon counting operation, are usually limited to an o ...
2018Objective evaluation of static beamforming on the quality of speech in noise
Hervé Lissek, Gilles André Courtois, Vincent Pierre Olivier Grimaldi
Beamforming is commonly used in devices such as in hearing instruments (HI) with a view to reducing noise. It consists in focusing on audio signals arising from a prescribed steering direction while suppressing those coming from other directions. The effic ...
European Acoustics Association2018Directional visible light communication signal enhancement using a varifocal micromirror with four degrees of freedom
We present the use of a micromirror to dynamically improve an optical wireless communiciations link. The signal-to-noise ratio (SNR) is improved by directing the output of a 675 nm laser diode modulated at 10 MHz toward a receiver and by varying the diverg ...
Spie-Int Soc Optical Engineering2016Learning spatio-temporal patterns in the presence of input noise using phase-change memristors
Stanislaw Andrzej Wozniak, Evangelos Eleftheriou, Angeliki Pantazi
Neuromorphic systems increasingly attract research interest owing to their ability to provide biologically inspired methods of computing, alternative to the classic von Neumann architecture. In these systems, computing relies on spike-based communication b ...
2016Interference Functionals in Poisson Networks
We propose and prove a theorem that allows the calculation of a class of functionals on Poisson point processes that have the form of expected values of sum-products of functions. In proving the theorem, we present a variant of the Campbell-Mecke theorem f ...
Ieee-Inst Electrical Electronics Engineers Inc2016Regulation of Cortical Dynamic Range by Background Synaptic Noise and Feedforward Inhibition
The cortex encodes a broad range of inputs. This breadth of operation requires sensitivity to weak inputs yet non-saturating responses to strong inputs. If individual pyramidal neurons were to have a narrow dynamic range, as previously claimed, then stagge ...
Oxford Univ Press Inc2015On Application Of Non-Negative Matrix Factorization for Ad Hoc Microphone Array Calibration from Incomplete Noisy Distances
Hervé Bourlard, Afsaneh Asaei, Mohammadjavad Taghizadeh
We propose to use non-negative matrix factorization (NMF) to estimate the unknown pairwise distances and reconstruct a distance matrix for microphone array position calibration. We develop new multiplicative update rules for NMF with incomplete input matri ...
