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.

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.

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!

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.

Projects

NETCARITY (A Networked Multisensor System for elderly people: health care, safety and security in home environment) if a project funded under EC IST FP6 as an Integrated Project, researching and testing technologies which will help older people to improve their wellbeing, independence, safety and health at home.

Events

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.

Main activities

Time-Of-Flight (TOF) measuring technique relies on the measurement of the round-trip time needed by a light pulse to travel from the measurement system to a target and back again, which has been actively investigated by the SOI research unit since 2002, exploring a number of different techniques.

Technologies

The first developments in 3D Vision at SOI were done in the framework of the Opto3D project since year 2000, with the development of an intelligent electro-optical sensor for driving scenarios detection and object recognition [1]. Since then, SOI investigated and developed a number of different operating principles for indirect time-of-flight imaging using CMOS technologies, from the simulation and development of the sensing device, to the integrated circuit and 3D camera system.
