Optical Fiber Sensors and Networks - Will They Further Brighten Our Future?

Steffen Lochmann
Hochschule Wismar, University of Applied Sciences: Technology, Business and Design
Germany
 

Brief Bio
Steffen Lochmann is professor at Hochschule Wismar, University of Technology Business and Design in Germany. He graduated at the Technical University of Dresden in 1981 and he obtained a PhD from Humboldt University of Berlin in 1984, where he worked on passive optical fibre components. In the same year he joined the Institute and Testing Centre for High Power Engineering Berlin. Here he was involved in investigations on fibre sensor and optical control networks for power plants. In 1991 he was appointed as an Assistant Professor and two years later as an Associate Professor of Telecommunications at the Asian Institute of Technology (Thailand). In 1993 he received the Dr. habilitas degree from the Humboldt-University of Berlin. After returning to Germany in 1995 he became the research manager of Advanced Photonic Systems GmbH Berlin. Here, his research activities focused on GHz-detectors, optical and electrical picosecond impulse generators and multimode fibre lasers. Since 1997 he has been working as a full professor at the Hochschule Wismar. His research areas includes a diversity of optical fibre sensors, sensor networks as well as optical code division multiplexing and optical MIMO technologies.


Abstract
The optical fiber sensor sector, which started as a spin-off branch of the telecom industry decades ago, has been transformed into an independent stand-alone research area and profitable market. This market with its wide diversity has been amazingly robust over the years.
Although the physical principles like intensity, phase, polarization, scattering or spectral sensing were studied in depth long ago and it seemed just a matter of a little bit of engineering to match a sensing principle to an application, we still experience constant and high annual growing rates in this market. The drivers behind it are mainly new sensor developments in terms of dimension, sensing sensitivity and dynamic range, extending fields of industry applications but also applications addressing harsh environments or EMI particularly.
Moreover, the need for deploying more and more sensors, sometimes even in a massive way, asks for new developments in sensor networks, too. Here the different fields of application may set demanding boundary conditions. E.g. smart structures may demand high sensing resolution and low or even no impact on its mechanical parameters. On the other hand, pipeline intrusion detection has to deal with very long monitoring distances.
Thus, new sensors, sensing concepts and related sensor networks continue to emerge and will do so in the future. Several advanced and latest examples, the author’s laboratory was involved with, will be addressed in the presentation to provide evidence of an further growing and diversifying optical fiber sensor market.



 

 

Indoor Air Quality Assessment - A New Challenge for Sensor Technology

Andrzej Szczurek
Wroclaw University of Technology
Poland
 

Brief Bio
Andrzej Szczurek obtained MSc in Solid State Physics (1978) from the University of Wroclaw. Since 1978 he is with Wroclaw University of Technology (WUT) Poland where he received PhD (1984) and DSc (2007). In 1986 he was a postdoctoral fellow at the Syracuse University, USA. Presently, he is a Professor and the head of the Laboratory for Sensor Techniques and Indoor Air Quality Studies at Faculty of Environmental Engineering WUT. In the period 2007-2013 he was responsible for one of major research tasks “Sensor system for measuring organic compounds” in the project "Detectors and sensors for measuring factors hazardous to environment - modeling and monitoring of threats", ?nanced by the EU via the European Regional Development Fund and the Polish state budget, within the framework of the Operational Programme Innovative Economy 2007-2013. In the period 2013-2016 he chaired the research project ” The variability of physical and chemical parameters in time as a source of comprehensive information about indoor air quality” funded by National Science Centre Poland. His main research interests are methods and techniques of air pollutants analysis with particular emphasis on the application of gas sensors for environmental assessment.


Abstract
Maintaining proper quality of ambient air is one of the greatest challenges faced by society today. However, over last few decades indoor air quality (IAQ) has become an important problem in many countries. Negative opinions arrive from different indoor environments, e.g. residential, occupational and institutional settings. Indoor air pollution is ranked as the highest risk to human being among all types of environmental problems. The consequences of poor IAQ are complex and not completely understood. The improvement of IAQ requires relevant information. The information about IAQ has a fundamental significance for building managers, policy makers, health professionals and scientists. Indoor air quality can be considered from two complementary perspectives – toxicity and the influence on comfort and wellbeing. Therefore, IAQ assessment is based on the perception of indoor air quality by occupants or the analysis of parameters describing physical and chemical properties of air inside building. The talk is focused on the second approach. In this field of measurements, the application of gas sensors is especially promising. The characteristics of: optical/non-dispersive infrared (NDIR) sensors; photoionization detectors (PID); metal-oxide-semiconductor (MOS) sensors; electrochemical (EC) sensors; catalytic sensors are presented. The potential applications of gas sensors are discussed. The attention is concentrated on the measurement equipment for qualitative and quantitative analysis of indoor air; direct-reading devices for detection of specific pollutants or indoor air quality indicators; sensor systems for classification of IAQ, characterization of odors (electronic noses), detection of events, diagnostics of IAQ. At the end, factors determining the progress of IAQ monitoring will be addressed.



 

 

Smart Communities: From Sensors to Internet of Things and toan Internet of Services

Stephan Olariu
Old Dominion University
United States
 
* CANCELLED *

Brief Bio
Stephan Olariuis a Professor of Computer Science at Old Dominion University, Norfolk, Virginia. He received his Bachelors, Masters and PhD from McGill University, Montreal, in 1980, 1982 and 1986,respectively.Over the years, Dr. Olariu has held many different roles and responsibilities as a member of numerous organizations and teams. Much of his experience has been with the design and implementation of robust protocols for sensor networks, IoT, and intelligent transportation systems and their applications to smart cities. His most recent research interests are in the area of vehicular clouds. Prof.Olariu is the author/coauthor of 4 books and over 350 papers.


Abstract
This keynoteaddress promotes the vision of Smart Communities (SC)as Internet of Servicessynthesized from interconnected hierarchies of resources available primarily within the corresponding community. At the basic level, resource may be physical, cyber or human entities. Our vision extends and generalizes the concept of cloud computing, where computational resources are bundled and offered as services on a metered basis. In our vision, in the Smart Communities of the (near) future a large number of services will be offered as utilities and sold on a metered basis. Importantly, most of these services will be aggregated and synthesized from a hierarchy of resources produced and shared by the community itself. In a nutshell, Smart Communities will offer various levels of service aggregations as utilities. In our vision, the members of the Smart Community or the visitors, will purchase as much or as little of these services as they find suitable to their needs and are billed accordingly. We suggest that the services offered by the SC are built on top of the resources of various IoT systems within the metropolitan community. In turn, these IoT systems will make their resources available to the SCin the context of a resource marketplace. Resources that can be sold in the marketplace include, but are not limited to, raw or aggregated sensor data at various resolution levels, shared and self-driven vehicles, private and public spaces and products, professional skills, traffic flow data, among many others. include but are not limited to sensor data, actuation capabilities, traffic views, etc.
