| Abstract: | In this paper,an experiment system which is composed of an ultraviolet laser pulse generator and a photomultiplier tube (PMT) is demonstrated to measure the spectra and time characteristics of laser induced fluorescence of engine oil.The generation of fluorescence is analyzed,and the way to measure the time resolved fluorescent spectra is proposed.The time resolved fluorescent spectra and the fluorescent life time of a kind of widely used engine oil named Yanshan TM engine oil are measured.The result of fluorescent spectral curve is identical to the results obtained with other methods. |
