| 摘 要： | A new laser induced fluorescence imaging system used for detecting and locating the petroleum pollu-tants is presented. A unique feature of the system was using a combination of a frequency-tripled Nd:YAG pulse laser and an image intensified CCD camera as imaging detector. The delay time of the system and the exposure time of the CCD are controlled by a delay generator. Petroleum pollutants on various backgrounds had been de-tected and located by this system. This imaging technique provides a useful noninvasive approach for the detection of petroleum pollutants, which can be used in remote sensing.
