报 告 内 容 简 介 | 报告人简介： Sune Svanberg obtained his PhD from University of Gothenburg, Sweden in 1972, and is since 1980 professor of physics at Lund University, Lund, Sweden. During 30 years, he was head of the Atomic Physics Division, and during 20 years founding director of the Lund Laser Centre. During 2011-2021 he was also a part-time distinguished professor at South China Normal University, Guangzhou. He holds 9 honorary doctor/professor appointments, is a member of 6 scientific academies, a fellow of 5 learned societies, and received numerous national and international awards. He is a recipient of the Chinese Friendship Award, and is an honorary citizen of Guangzhou. He served on many boards and committees, including a 10-year membership of the Nobel Committee for Physics of the Royal Swedish Academy of Sciences. Based on a long career in basic atomic spectroscopy and high-power laser/matter interactions, his current research interests focus on laser spectroscopic applications to the environmental, ecological and biomedical fields. He has a large number of patents and patent applications and helped forming spin-off companies.
报告内容简介： Laser spectroscopy is a flourishing research area, which had major impact in science during recent years. In applied laser spectroscopy, the fields of combustion diagnostics, atmospheric remote sensing, agriculture and ecology, as well as biomedicine are prominent. A brief overview of certain applications of laser spectroscopy is given, with emphasis on the environmental, ecological, and agricultural areas, as based on the experience of the author within these fields. Optical probing of the atmosphere using active remote sensing techniques of the laser-radar type will be discussed. Atmospheric objects of quite varying sizes can be studied. Mercury is the only pollutant in atomic form in the atmosphere, while other pollutants are either molecular or in particle form. Light detection and ranging (Lidar) techniques provide three-dimensional mapping of such constituents. Recently, the techniques have been extended to the ecological field. Monitoring of flying insects and birds is of considerable interest, and several projects have been pursued in collaboration with biologists. Fluorescence lidar allows remote monitoring of vegetation and historical building facades. Drone-based techniques are now also augmenting the possibilities of fluorescence mapping of the environment, and in agriculture. Non-destructing inspection of food packages based in gas monitoring is a further emerging field with substantial potential. The importance of cross-disciplinary work in solving important societal problems is emphasised. |
