Abstract :
Laser methods for the remote detection of oil present as a pollutant in the sea water using Raman backscattering and back scattered fluorescence are discussed and compared. The scattering spectra of oils excited by a cw Ar ion laser which were obtained by using a laser Raman spectro meter are described. Theoretical performance of a laser-Raman rader for the remote detection of oil are discussed. The back scattering spectra of oils in the sea water obtained by a laser rader scheme are also described.
