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

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

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.

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.



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

Stephan Olariu
Old Dominion University
United States

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.

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.
