Abstract
A new method of remote sensor of micro amount oil in water by laser induced fluorescence is presented. In the detecting system, a MODEL YAG571C pulsed triplicated laser (Continuum Corporation of U.S.A.) With wavelength of 355nm, pulse duration of 35ps, pulse energy of 3mJ was used as exciting source. Using multi-track spectrograph as the detector, a computer as the data processor, 355nm laser as the master trigger which contact the SRS-DG535 four channel digital delay/pulse generator, we have obtained fluorescence lifetime of some aromatic pollution materials in water and relevant 3D (time-wavelength-fluorescence intensity) fluorescent diagrams. By analyzing the spectra property, it is possible to discriminate the oil pollution types.
