报告摘要:
Distributed optical fibre sensors have attracted a sustained interest and experienced a tremendous development recently, since they offer key advantages such as the possibility to turn the fibre into a real optical nerve. We shall review the physical principles behind the sensing process and the main types of distributed sensors, illustrated by several examples, and we shall show the latest developments in this promising field.
 
报告人简介:
Luc Thévenaz received the M.Sc. degree and the Ph.D. degree in physics from the University of Geneva, Switzerland. In 1988 he joined the Swiss Federal Institute of Technology of Lausanne (EPFL) where he currently leads a research group involved in photonics, namely fibre optics and optical sensing. Research topics include Brillouin-scattering fibre sensors, slow & fast light, nonlinear fibre optics and laser spectroscopy in gases. He achieved with his collaborators the first experimental demonstration of optically-controlled slow & fast light in optical fibres, realized at ambient temperature and operating at any wavelength since based on stimulated Brillouin scattering. He also contributed to the development of Brillouin distributed fibre sensing by proposing innovative concepts pushing beyond barriers. He recently developed a simple technique to generate perfect Nyquist pulse to boost the data rate in already installed optical links.
During his career he stayed at Stanford University, at the Korea Advanced Institute of Science and Technology (KAIST), at Tel Aviv University and at the University of Sydney. In 2000 he co-founded the company Omnisens that is developing and commercializing advanced photonic instrumentation. He is Fellow of the Optical Society of America, Senior Member of the IEEE and Editor in 3 major scientific journals.
