Applications of Laser-Scattering for the Remote Detection of Water Pollutants

Laser-induced fluorescence and Raman scattering produce characteristic spectral signatures of molecular species. The detection and analysis of such signatures from polluted water provide a non-invasive method for pollution monitoring. The techniques, present status and future prospects for the use of such laser-based systems for the remote surveillance of surface water pollution and for the real-time monitoring ofpollution for waste water process control are analysed.
