Aggregating Spatial and Photometric Context for Photometric Stereo
Photometric stereo, a computer vision technique for estimating the 3D shape of objects through images captured under varying illumination conditions, has been a topic of research for nearly four decades. In its general formulation, photometric stereo is an ...
EPFL2024A Gradient-Gated SPAD Array for Non-Line-of-Sight Imaging
Edoardo Charbon, Pouyan Keshavarzian, Jiuxuan Zhao, Francesco Gramuglia, Myung Jae Lee
Time-resolved non-line-of-sight (NLOS) imaging based on single-photon avalanche diode (SPAD) detectors have demonstrated impressive results in recent years. To acquire adequate number of indirect photons from a hidden scene in the presence of overwhelming ...
Ieee-Inst Electrical Electronics Engineers Inc2024Silicon CMOS and InGaAs(P)/InP SPADs for NIR/SWIR detection
Applications demanding imaging at low-light conditions at near-infrared (NIR) and short-wave infrared (SWIR) wavelengths, such as quantum information science, biophotonics, space imaging, and light detection and ranging (LiDAR), have accelerated the develo ...
EPFL2024Demonstration of particle tracking with scintillating fibres read out by a SPAD array sensor and application as a neutrino active target
Edoardo Charbon, Claudio Bruschini, Paul Mos, Kodai Kaneyasu, Michael Alan Wayne
Scintillating fibre detectors combine sub-mm resolution particle tracking, precise measurements of the particle stopping power and sub-ns time resolution. Typically, fibres are read out with silicon photomultipliers (SiPM). Hence, if fibres with a few hund ...
New York2024Evaluation of HPK n plus -p planar pixel sensors for the CMS Phase-2 upgrade
Varun Sharma, Konstantin Androsov, Xin Chen, Rakesh Chawla, Werner Lustermann, Andromachi Tsirou, Alexis Kalogeropoulos, Andrea Rizzi, Thomas Muller, David Vannerom, Albert Perez, Alessandro Caratelli, François Robert, Davide Ceresa, Yong Yang, Ajay Kumar, Ashish Sharma, Georgios Anagnostou, Kai Yi, Jing Li, Stefano Michelis, David Parker, Martin Fuchs
To cope with the challenging environment of the planned high luminosity upgrade of the Large Hadron Collider (HL-LHC), scheduled to start operation in 2029, CMS will replace its entire tracking system. The requirements for the tracker are largely determine ...
Amsterdam2023Aperture-Controlled Fabrication of All-Dielectric Structural Color Pixels
Olivier Martin, Philippe Renaud, Arnaud Bertsch, Daniel Migliozzi, Evgenii Glushkov, Clémentine Sophie Sarah Lipp, Hsiang-Chu Wang, Audrey Zoé Marie Jacquillat
While interference colors have been known for a longtime, conventionalcolor filters have large spatial dimensions and cannot be used tocreate compact pixelized color pictures. Here we report a simple yetelegant interference-based method of creating microsc ...
AMER CHEMICAL SOC2023Computational Imaging SPAD Cameras
Vision systems built around conventional image sensors have to read, encode and transmit large quantities of pixel information, a majority of which is redundant. As a result, new computational imaging sensor architectures were developed to preprocess the r ...
EPFL2023Burst Vision Using Single-Photon Cameras
Edoardo Charbon, Paul Mos, Mohit Gupta
Single-photon avalanche diodes (SPADs) are novel image sensors that record the arrival of individual photons at extremely high temporal resolution. In the past, they were only available as single pixels or small-format arrays, for various active imaging ap ...
IEEE COMPUTER SOC2023MALTA-Cz: a radiation hard full-size monolithic CMOS sensor with small electrodes on high-resistivity Czochralski substrate
Edoardo Charbon, Francesco Piro, Ashish Sharma
Depleted Monolithic Active Pixel Sensor (DMAPS) sensors developed in the Tower Semiconductor 180 nm CMOS imaging process have been designed in the context of the ATLAS ITk upgrade Phase-II at the HL-LHC and for future collider experiments. The "MALTA-Czoch ...
Bristol2023Learned Compressive Representations for Single-Photon 3D Imaging
Edoardo Charbon, Claudio Bruschini, Andrei Ardelean, Mohit Gupta
Single-photon 3D cameras can record the time-of-arrival of billions of photons per second with picosecond accuracy. One common approach to summarize the photon data stream is to build a per-pixel timestamp histogram, resulting in a 3D histogram tensor that ...
