Quantum imaging with SPAD arrays (Conference Presentation)

Single Molecule Spectroscopy and Superresolution Imaging XIII, 2020
The emerging field of quantum imaging introduces new methods to overcome classical limitations in optical microscopy. A detection apparatus capable of analyzing the quantum signature of light, is a crucial component in the heart of any such method. We present a novel quantum imaging modality, based on a state-of-the-art single photon avalanche diode (

Drone segmentation and orientation detection using a SPAD array camera

Defense + Commercial Sensing, 2022
The recent development of single-photon avalanche diode (SPADs) arrays as imaging sensors with both picosecond binning capabilities and single photon sensitivity has led to the rapid development of time-of-flight imaging systems. When used in conjunction

Preliminary Test Measurements of the SPAD Array

2004
This is a progress report on preliminary test measurements aimed to evaluate the performance of new Single Photon Avalanche Diodes (SPAD) developed by ST Microelectronics. Various samples with different dimensions (from 10 to 100 μm diameter) and two 5x5 arrays (20 and 40 μm) are manufactured by STM; some of which have been characterized.

Room temperature 96x96 InGaAs/InP SPAD array for SWIR imaging

Environmental Remote Sensing
We present a 96x96 InGaAs/InP single photon avalanche diode (SPAD) array for detection at 1550nm wavelength. The pixels have a diameter of 15μm and a 25μm pitch, resulting in a fill factor of 28.3%.

Frame-filtered ghost imaging with a SPAD array used {both as} a multiple "bucket" detector and an imaging camera

Applied Optics
An approach to ghost imaging with a single SPAD array used simultaneously as a several-pixel"bucket"detector and an imaging camera is described. The key points of the approach are filtering data frames used for ghost-image reconstruction by the number of

SPAD arrays for parallel photon counting and timing

2010 IEEE Photinic Society's 23rd Annual Meeting, 2010
We present a detection module based on a linear array of Single-Photon Avalanche Diodes (SPAD) made in a standard CMOS technology. The monolithic chip is employed both to count photons at very high frame-rate (up to 4,000,000 frames/s, with 250 ns time tagging resolution) and to mark photon arrival time with 50 ps timing precision.

Planar technologies for SPAD arrays with improved performances

SPIE Proceedings, 2012
In the last years many progresses have been made in the field of Silicon Single Photon Avalanche Diodes (SPAD) thanks to the improvements both in device design and in fabrication technology. For example, the use of custom fabrication processes has allowed a steadily improvement of SPAD performance in terms of active area diameter, Dark Count Rate (DCR),
