Paper Abstract

Recently we have developed a lidar fluorescence sensor system, consisting of a compact Nd:YAG laser with second and third harmonics generation, mounted on a Newtonian receiver coupled to a small monochromator with a ICCD detection unit. The laser radiation induces fluorescence on a remote target and fluorescence spectra are recorded. Substances like DOM, chlorophyll and other plants pigments, algae and phytoplankton, crude oil, etc. can be identified in this way. Preliminary laboratory work was done on various substances. The concentration of the trace compound in water is usually obtained by normalizing the integrated fluorescence intensity respect to the Raman peak of water at 402 nm. Preliminary results of laboratory calibration measurements on water pollution and vegetation will be presented.
