A method of remote measuring of oil film thickness on polluted water s
urface by a fluorescent lidar is suggested. The method was tested in a
laboratory experiment. The eximer laser was used as a source of fluor
escent excitation. It was shown that this method can be used for remot
e determination of the oil films on polluted water surfaces. A possibi
lity of using eximer lasers for remote determination of oil film thick
ness is discussed.
