Single-Photon Imaging


IRIS will be at ISSCC 2015 ( with:

- A full paper titled 'A 160x120-Pixel Analog-Counting Single-Photon Imager with Sub-ns Time-Gating and Self-Referenced Column-Parallel A/D Conversion for Fluorescence Lifetime Imaging' presented by Matteo Perenzoni within Session 11 'Sensors and Imagers for Life Sciences'. The sensor will be also presented at the Demonstration session on Monday 23rd between 4:00-7:00pm: come to see our live demo!

- A Tutorial on 'CMOS Sensors for 3D Imaging' presented by David Stoppa on Sunday 22nd.

The well-known Image Sensors World blog publishes an extract of the image sensor-related advance program of the 2015 International Solid-State Circuits Conference.

The IRIS research unit is participating with a tutorial on 3D imaging techniques by D. Stoppa, and a regular paper on a SPAD-based imager for fluorescence lifetime imaging by M. Perenzoni, N. Massari, D. Perenzoni, L. Gasparini, and D. Stoppa.

Within the framework of the SiQuro project, Dr. Damien Stucki from ID Quantique (Geneve, Switzerland) is visiting us and giving a seminar entitled “Quantum random number generator”.


We would like to thank all the contributors and participants to the 2013 Researchers' Night, which has been a wonderful and successful event!

A special thank to all the people who visited our booth inside the Muse museum, playing with our photons and leaving their thermal fingerprint... hope to see you next time with new and even more exciting stuff to show!

Vorremmo ringraziare tutti quanti hanno contribuito e partecipato alla Notte dei Ricercatori 2013, che e' stato un bellissimo evento di successo!

The 27th of September, 2013, the SOI research unit will be at the Researchers' Night 2013, held in the Muse Trento museum.

The following demos and installations will be shown:

  • Advanced diagnosys techniques
  • Seeing the invisible: the heat
  • Human-machine interaction
  • What happens when shooting a photo?

Come, meet and have fun with us!

Four papers highlighting the latest developments of the SPADnet European project (, of which SOI is part, have been accepted as oral presentation in this year’s Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), to take place in Seoul, South Korea, from the 27th of October to November 2nd. The papers and its sessions are:

Two SOI papers have been accepted at the 2013 European Solid-State Circuits Conference (ESSCIRC), to be held on September 16-20 in Bucharest, Romania. Both papers will be presented at the CMOS Image Sensors Session (B6L-F) on Wednesday, September 18:

  • "Compact Analog Counting SPAD Pixel with 1.9% PRNU and 530ps Time Gating " by L. Pancheri, E. Panina, G.-F. Dalla Betta, L. Gasparini, D. Stoppa.
  • "A 80µW 30fps 104 X 104 All-nMOS Pixels CMOS Imager with 7-Bit PWM ADC for Robust Detection of Relative Intensity Change" by M. Benetti, M. Gottardi, Z. Smilansky.


The NAOMI project ("NAno on MIcro approach to a multispectral analytical system for protein assays") tackles the challenge to develop miniaturized, multispectral protein chips, focusing on the combination of nano and micro technologies to deliver compact, reliable and potentially low cost diagnostic instruments with improved analysis performances.

SiQuro (On silicon chip quantum optics for quantum computing and secure communications) is a project funded by the Autonomous Province of Trento aiming at building a silicon platform for secure quantum computing and communications.


The development of circuits for pulsed time-of-flight (TOF) laser range finders has been one of the main areas of research at the Electronics Laboratory of University of Oulu already over 30 years. Head of the laboratory and the group is professor Juha Kostamovaara. There are many applications for pulsed TOF laser radars such as the positioning of tools and vehicles, the profiling and scanning of surfaces, anti-collision radars and traffic perception, for example.
