Terahertz Radar for Stand-Off Through-Clothes Imaging

Keynote Speaker: Dr. Goutam Chattopadhyay

Security experts around the world have long been demanding an imaging system for detection of weapons or contraband from a safe stand-off distance concealed on persons. There has been some demonstration of active and passive millimeter- and submillimeter-wave imagers in recent years. However, passive imagers at terahertz frequencies do not provide enough contrast as they rely on the difference between the emitted radiation and the background "sky" temperature. Unfortunately, due to high atmospheric absorption at these frequencies, the background sky is very warm, providing very little contrast. On the other hand, active terahertz imagers have to deal with glint and require the imaging objects to be precisely placed at certain angles. We, at JPL, developed a radar based imaging system at terahertz frequencies which overcomes all these challenges and is capable of near video-rate imaging. In effect, the terahertz radar imager does an electronic strip-down revealing person-borne illicit materials and weapons from a safe stand-off distance. In this talk, a overview of the state of terahertz imagers will be provided, specifically focusing on radar imagers.

Falling Detection and Motion Reconstruction of Elderly People: Sensors Based Approach

Keynote Speaker: Distinguished Professor Yueh-Min Huang

At present, there are many studies of falling accident detection, while most employed image detection or used single acceleration sensors for identification. Recognition by image detection has very high operational complexities, and infringe on privacy. Single acceleration sensors have very high accuracy in falling detection, however, the accuracy of judging body posture requires highly complex operations, and thus, cannot provide real-time notice for accidental falling detection. This study explored the collaborative detection of body behavior modes and accidental falling incidents by using multiple tri-axis acceleration sensors. Information is provided by sensors distributed over the body that transmit positions, by radio transmission devices to a computer, in order to analyze and recognize current body behavior status, which create a warning when a falling accident happens. After a falling accident occurs, more information of the sudden incident, such as body posture and impact of crucial position, can be provided to medical personnel for more accurate diagnosis.

Lossy mode resonances - based fiber optic sensors

Keynote Speaker: Professor Ignacio R. Matías

During the last decades, much research has been done in the field of semiconductor and metal clad optical waveguides. In both cases, the clad introduces losses to the propagation of light in the optical waveguide. Depending on the properties of the cladding or the thin-film, three main cases can be distinguished. The first case, occurs when the real part of the thin-film permittivity is negative and higher in magnitude than both its own imaginary part and the permittivity of the material surrounding the thin-film (i.e. the optical waveguide and the surrounding medium in contact with the thin-film). In this case, coupling occurs between light propagating through the waveguide and a surface plasmon, which is called surface plasmon polariton or surface plasmon resonance (SPR). The second case occurs when the real part of the thin-film permittivity is positive and higher in magnitude than both its own imaginary part and the material surrounding the thin-film. Some authors consider these modes as long-range guided modes [3], whereas others call them lossy modes. The third case, occurs when the real part of the thin-film permittivity is close to zero, while the imaginary part is large. This case is known as long-range surface exciton polariton.

During the last years, hundreds of publications have been devoted to the SPR, whereas the number of publications devoted to lossy modes resonances (LMR) is quite low. In fact, all of them correspond to theoretical works. Moreover, in our knowledge, the utilization of LMR for sensing purposes has been used very recently in our group for the first time. For the sake of truth, some works using LMR had been previously published, but authors misunderstood these resonances with others, mainly with SPR.

The use of Sensing Technology in Agrometeorology

Keynote Speaker: Professor Philip Sallis

Over the past three years the Geoinformatics Research Centre (GRC) at Auckland University of Technology has been working in the research domain known as agrometeorology. As part of this work the GRC has designed and built a set of terrestrial WSN monitoring instruments. The real-time data logged by these instruments is being analysed for trends in climate variation and for the anticipation of events in Nature that influence crop production yield and quality. The instruments are located in some 30 sites across 7 countries.

This presentation describes the project and the international R&D collaboration that has grown from a single research question into a number of discrete yet related data analysis, design and modelling projects, some of them with commercial outcomes.


Philip received his PhD degree in Information Science in 1979 from the Faculty of Engineering at The City University London. Previously he studied mathematics and computer science at Victoria University of Wellington, New Zealand.

Holding academic position in London, Sydney and Dunedin, in 1987 Philip was appointed Foundation Professor of Information Science at The University of Otago. During this time building on the foundation topics of computer science, he built a new curriculum focusing on innovative methods for data analysis and modelling, software engineering, geospatial information processing and knowledge based systems for automated intelligent decision making.

In 1999 he moved to the newly formed Auckland University of Technology where until 2009 he was the Deputy Vice Chancellor. In addition to his role as deputy for the Vice Chancellor he led the academic and research activity build for the new university and created the AUT Technology Park, which is now the Business Innovation Centre and helped form AUT Enterprises Limited, the University's commercialisation company. He is a Director and currently is the Chair of the Board of Directors for this company.

In 2009 Philip 'retired' from his role as Deputy Vice Chancellor and has returned to full-time research, combining his background in mathematics, software engineering and geocomputation. . He now leads a small team of researchers in the Geoinformatics Research Centre (GRC) at AUT and has an adjunct research professorship at the Catholic University of Maule in Chile, in a research laboratory associated with the GRC at AUT. His international research collaboration extends through a real-time network of WSN agrometeorological instruments in 7 countries to form a large terrestrial monitoring and modelling system that combines scientific research with end user information needs for precision agronomic decision making.

Philip has been President of the New Zealand Computer Society and was Founding Chair of the NZ Chapter of the Association for Computing Machinery (ACM). He is currently a member of the Royal Society of New Zealand, the IEEE (and Nth Branch Committee in NZ) and Hon Chair of the IEEE Instrumentation and Measurement Society (NZ Chapter). He is a Lifetime Member of the International Association of Mathematical Geosciences and Associate Editor for the International Journal on Sensing and Intelligent Systems. He has served on and chaired numerous Government commissions and industry boards and is a Member of the NZ Institute of Directors with experience as a board member for various companies including his own professional consulting and software innovations company.

Philip is a regular keynote speaker and presenter at conferences with some 300 plus journal articles, books, conferences papers and commissioned reports in his name.
