Single-Photon Imaging

Projects

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.

SPADnet (Fully Networked, Digital Components for Photonstarved Biomedical Imaging Systems) is a research project funded by the EU within the ICT Theme of its Seventh Research Framework Programme (FP7). SPADnet will build ring-assembly modules for Positron Emission Tomography (PET) medical imaging, and carry out performance tests in a PET system evaluation test bed.

News

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.

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

Single Photon Avalanche Diodes (SPADs) allow detecting the arrival of a single photon for each pixel, potentially with the possibility of recording the arrival time. Since 2004, SOI research unit has been conducting research in the field of devices and circuits for single photon detection.
