Coupling a recurrent neural network to SPAD TCSPC systems for real-time fluorescence lifetime imaging
Edoardo Charbon, Claudio Bruschini, Andrei Ardelean, Paul Mos, Yang Lin
Fluorescence lifetime imaging (FLI) has been receiving increased attention in recent years as a powerful diagnostic technique in biological and medical research. However, existing FLI systems often suffer from a tradeoff between processing speed, accuracy, ...
Berlin2024Imaging sensor device using an array of single-photon avalanche diode photodetectors
Edoardo Charbon, Andrei Ardelean
The invention relates to an Imaging sensor device in a stacked arrangement comprising: - a pixel array tier comprising a plurality of pixel segments each having a plurality of pixels for photon detection each providing a digital pixel output; - a processin ...
2024Computational 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 ...
EPFL2023Massively parallel, real-time multispeckle diffuse correlation spectroscopy using a 500 × 500 SPAD camera
Edoardo Charbon, Claudio Bruschini, Andrei Ardelean, Paul Mos, Arin Can Ülkü, Francesco Marsili, Michael Alan Wayne
Diffuse correlation spectroscopy (DCS) is a promising noninvasive technique for monitoring cerebral blood flow and measuring cortex functional activation tasks. Taking multiple parallel measurements has been shown to increase sensitivity, but is not easily ...
2023SoDaCam: Software-defined Cameras via Single-Photon Imaging
Edoardo Charbon, Andrei Ardelean, Mohit Gupta
Reinterpretable cameras are defined by their post-processing capabilities that exceed traditional imaging. We present "SoDaCam" that provides reinterpretable cameras at the granularity of photons, from photon-cubes acquired by single-photon devices. Photon ...
Ieee Computer Soc2023Learned 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 ...
