Abstract

It is presented the results of oil products and dissolved organic matter water pollution detection and mapping. The simultaneous detection of laser induced fluorescence and water molecule Raman scattering signals gives the possibility of chlorophyll "a" concentration measurements and biological productivity evaluations. The lidar setup includes a NdYAG laser, compacted and stable to vibration, with frequency doubling (second harmonic pulse energy 200 mJ, pulse duration 10 ns, repetition rate 10 Hz); a receiving - transmitting device with a mirror telescope of 15 cm diameter; a polychro
