Abstract:
A laboratory experiment is discussed which simulates lidar fluorosensing of oil films on the sea surface at UV wavelengths. Three different mixtures of lasing gases, KrF, XeCl and N2 , were used while a fourth wavelength was given by a dye laser. It turns out that films having a thickness as low as 0.01 microm can be detected; the limiting factor resides mainly in the background fluorescence of water. Best results have been obtained with the XeCl excimer laser.
