IMAGIC Seminar 2007 - Report

Seminar day: Imaging technology for non-visible wavelengths

At the IMAGIC seminar day, on September 13th 2007, more than 50 people gathered in the Science Tower, Kista, Stockholm, to hear presentations from both national and international speakers and to socialize with their colleagues. More than half of the participants came from industry, while the remainder came from universities, institutes and other organisations.

The participants were welcomed to the event by Leif Bergström, the chairman of IMAGIC’s board of directors. This was followed by an overview of IMAGIC and its activities by the Centre Manager, Jan Andersson.

The first technical presentation was given by Dr. Sarath Gunapala from the Jet Propulsion Laboratory in California, USA. Dr Gunapala has worked for many years on detection and imaging of thermal infrared wavelengths, and is regarded as a pioneer in the field of QWIP IR detectors. Dr Gunapala is now a member of IMAGIC’s scientific advisory board. At the seminar, he presented the physics and applications of next generation photon detectors for thermal infrared.

This was followed by the second international speaker, Dr. Jean-Yves Duboz from CRHEA, CNRS, France. Dr Duboz has worked for many years on the development of gallium nitride material (GaN) and its associated alloy aluminium gallium nitride (AlGaN) for use in the detection and imaging of UV radiation. Dr. Duboz presented his latest results in his talk “AlGaN detectors and arrays for UV detection”.

A third wavelength region of active interest to IMAGIC is X-ray detection. An overview of detection theory, detector types and applications was given by Dr. Jan Linnros from the Royal Institute of Technology (KTH) in Stockholm. Dr. Linnros has led the development of a novel x-ray imaging detector, which will now be commercialized by the new spin-off company Scint-X.

Signal processing electronics for image sensors was then presented by Prof. Robert Forchheimer from the University of Linköping. Prof. Forchheimer is known as the originator of model-based picture coding, and also has worked on the development of integrated circuits for picture analysis. He is now also a member of IMAGICs scientific advisory board.

A presentation on the use of imaging in security applications was the next presentation by Mikael Lindgren from Saab Bofors Dynamics AB. He showed, among others, examples of how infrared imaging combined with other technologies can be used for surveillance and area protection networks, and how terahertz imaging can be used to detect objects that are not visible to the naked eye.

Anders Söderbärg from NOTE AB gave a novel presentation without slides, where he gave a short overview of NOTE’s activities making modules from chips, and then invited the audience to ask questions so that he could provide the information they required.

The final presentation was given by Gösta Forsén of Optronic AB, in which he presented four keys for the development of products based on optical components.
