Activities in Passive and Active Submillimetre-Wave Imaging at VTT/MilliLab

May 2, 2012
EE Conference Room
Hosted by: Columbia Integrated Systems Laboratory
Speaker: Dr. Artu Luukanen , Director (Millimetre Wave Laboratory of Finland)


Both active and passive submillimetre-wave stand-off imaging systems are under development for security imaging applications. The drivers for operation at higher frequencies have been the desire for better image resolution, smaller optics package, reduced susceptibility to specular reflections from the human skin and capability for stand-off imagery. In the talk I summarize our efforts on devices, components and systems which could eventually pave the way for fast, real time, high-resolution imaging systems for the submillimetre-wave range.

Speaker Biography

Arttu Luukanen (born 1972, native of Finland) received his M.Sc. degree from the University of Helsinki, Finland in applied physics in 1999. He was awarded a Ph.D. in 2003 from the University of Jyväskylä, Finland, also in applied physics. Dr. Luukanen’s professional career began as a research assistant at Metorex International Oy, a Finnish company specializing in analytical X-ray instruments for the metal industry and a supplier of X-ray detectors for several space science missions of the European Space Agency ESA, NASA, and NASDA. In 1996, Arttu Luukanen began investigating technologies for passive millimeter wave imaging for concealed weapons detection. This research culminated in passive scanned imagery of objects taken with an imaging system utilizing antenna-coupled microbolometers as the detectors. Dr. Luukanen continued his bolometer research as a graduate student at the University of Jyväskylä, Department of Physics under a joint ESA contract with Metorex. His Ph.D. research focused on the development of ultra-sensitive transition-edge microcalorimeters and microbolometers for X-ray and THz sensing applications. After completing his Ph.D., Dr. Luukanen took a research scientist position at VTT Technical Research Centre of Finland. From 2003 to 2005 he worked as a guest researcher at the National Institute of Standards and Technology in Boulder, Colorado (USA) developing an active millimetre-wave imaging system based on antenna-coupled microbolometers. In 2005, Dr. Luukanen was nominated as the Director of MilliLab, the Millimetre Wave Laboratory of Finland. Since 2006, Dr. Luukanen has served as the chairman of IEEE Electron Devices/Microwave Theory & Techniques and Antennas & propagation Chapters of the IEEE Finland Section.
