Title: Laser Spectroscopy Applied to the Environmental, Ecological and Food Safety Areas

Abstract: An overview of optical probing of the atmosphere will be given, where mostly active remote- sensing techniques of the laser-radar type will be covered, but also some passive techniques employing ambient radiation. 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 provides three-dimensional mapping of such constituents. Fluorescence Lidar also allows remote monitoring of vegetation and historical building facades. Examples from Lidar work in Lund and in Guangzhou will be given. 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. Laser spectroscopy also allows for non-intrusive quality control of pharmaceutical preparations and foods. The talk emphasizes the value of cross-disciplinary work to help solving important societal issues.
