Single-Photon Imaging


The Researchers' Night 2015, held on the 25th of September, was a great success!

We really would like to thank the hundreds of you who visited our booth and got excited together with us about science! It has been really a wonderful experience also for us in getting in touch with all of you.

Stay tuned as we won't miss the chance to grab your attention even more at the next event!

In the framework of the SiQuro project, FBK-IRIS and University of Trento developed a patented technology able to exploit the quantum nature of light in order to generate truly random numbers, a fundamental brick in cryptography, in an extremely compact footprint.

The local newspaper talks about us in this article.

IRIS will be present at the IISW next week in Vaals (The Netherlands) with the 7.17 poster "Compact time-gated analog counting SPAD-based pixels for high resolution, single-photon, time-resolved imagers". Meet you there!

The SPADNet project has successfully achieved its objectives with excellent results: the IRIS research unit is proud of having been part of this amazing collaboration and having taken part in the development of such a powerful technology.

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.


MILA (Miniaturized Imaging Laser Altimeter) is an ESA project aiming at the development of a compact imaging altimeter for the future ESA mission in order to provide a support for the global navigation system in the approach and landing of flying spacecrafts.

Molecular imaging (MI) and Proton Therapy (PT) have become fundamental tools for the diagnosis and treatment of diseases such as cancer. Innovation in this field is very strong aiming at improving the imaging capability. The most important development over the last few years is the use of a novel solid-state photo-detector (Silicon Photomultipliers, SiPMs) that can replace the traditional vacuum-based photo-multiplier tubes. This sensor opens the possibility to combine different imaging modalities and to develop compact, light and portable systems with higher performance.


Fluorescence Lifetime Imaging Microscopy (FLIM) is a powerful tool for the analysis of biological samples, enabling the extraction of more information by detecting not only the intensity of the fluorescence but also its lifetime.
