IMAGIC Seminar days 2012

“Imaging Integrated Components and Systems”

A large public attended the IMAGIC seminar days 2012 which were hosted by Acreo on Oct 9th and 10th in the Electrum conference facilities in Kista.

The aim of the conference this year was to publicize the results achieved within IMAGIC during the past 6 years. This was achieved through several presentations from the IMAGIC portfolio of technical advances. This included:Leif Bergström, chairman of the IMAGIC board introduces IMAGIC

  • results from the IMAGIC long-wave infrared (LWIR) detector activity involving quantum dot and type II superlattice technology, both of which can decrease the cost and complexity of high performance LWIR cameras.
  • a novel technique for isotropic detection of x-rays by a detector with a cubic form, together with its manufacturing technique. This can reduce the dependence of the detection signal on the angle of the incoming radiation, leading to more accurate measurement and new applications for this technology.
  • sensitive detection of ultraviolet radiation through the use of novel wide bandgap materials. This can lead to smaller and lower-cost cameras and detectors for environmental and industrial surveillance.
  • a low-cost technique based on microbolometers for detection of LWIR, which is of great interest for use in automotive applications such as Night Vision.
  • the design of read-out electronics, which is a necessary part of all cameras. This talk was illustrated by a description of the read-out integrated circuit (ROIC) designed for the IMAGIC bolometer.

Also Nils Nordell, manager of the Electrum Laboratory which is highly utilized by the IMAGIC team, presented the capabilities and prospects of the lab, before offering a tour during the lunch break.

Hedda Malm ät IMAGIC 2012    Amir Karim at IMAGIC 2012

Hedda Malm and Amir Karim present the IMAGIC LWIR activity

The IMAGIC presentations were supplemented by selected external speakers from Sweden and other European countries.

International speakers included Chee Hing Tan (Sheffield University, England), Alberto Tosi (Politecnico di Milano, Italy), and Jan Vermeiren (Xenics nv, Belgium), who presented their achievements and products within the short-wave IR technology area, from materials through devices to cameras. Among many other applications, this wavelength range is very popular for surveillance, as it permits viewing through fog, smoke and haze, as well as permitting 3D imaging at eye-safe wavelengths.

Another international speaker was Michael Fiederle (Freiburg Materials Research Center, Germany) who presented the current status and prospects of x-ray detectors based on gallium arsenide (GaAs). GaAs is a desirable material for the production of x-ray detectors, as it is a mature material technology and more environmentally compatible than the cadmium telluride (CdTe) commonly used today.

Imaging at terahertz wavelengths has been highly publicized as a security screening technology. Artuu Luukanen (VTT, Finland) showed how antenna-coupled microbolometers can be used to detect terahertz radiation, and the challenges that remain to be met with this technology.

In addition to the technical presentations, an exhibition was also laid out about IMAGIC achievements and activities. This included hardware exhibits such as processed devices and the bolometer ROIC, as well as film clips and posters. Achievements other than technical were also illuminated, such as stories about how IMAGIC students have progressed after their time here.

An informative and enjoyable two days was experienced by all.
