Single-Photon Imaging


IRIS team offers one fully funded PhD research fellowship in the field of CMOS readout ASIC for single-photon detectors.

Application details are available through the University of Trento website:

The IRIS grant, scholarship B2, is fully sponsored by FBK and the candidate will be hosted within FBK facility under direct supervision of IRIS senior researchers, worldwide experts in the field of single-photon detectors.

The 3rd Harvest Imaging Forum, organized by Albert Theuwissen, will see IRIS group leader, David Stoppa, as speaker.

David shall talk about “3D Imaging with Time-of-Flight : Solid-State Devices, Circuits and Architectures”, in Voorburg (The Hague), The Netherlands. The forum will be held in December 2015.

Mark it in your agenda!

The IRIS team would like to thank the participants of the tutorial on 3D imaging held by David Stoppa, and who attended the demo session plus the oral presentation of the time-gated single photon imager by Matteo Perenzoni.

This year's ISSCC has been a great event for us, beside being an outstanding conference on its own: the tutorial attendance has been excellent, the demo session busy and rewarding as it should be, and a really crowded room was looking forward to the very interesting papers of the "Sensors and Imagers for Life Sciences" session.

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:


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.
