英文摘要	By refering to the principle and structure of the Mueller matrix ellipsometry, a LIF ellipsometric setup with rotating waveplate was built up to investigate the polarization characterization of laser-induced fluorescence from the simulated oil spill samples under excitation of laser with different elliptical polarization states. The setup was calibrated with the Eigenvalue Calibration Method at first to obtain the exact modulation states of both the polarization modulation matrix W(lambda) and the polarization analyses matrix A(lambda). Then with the fluorescence intensity matrices Flu(lambda) measured by sequentially modulation of the polarization-state generator unit and the polarization-state analyzer unit, LIF Mueller matrices of light, medium and heavy crude oil samples as well as diesel were established and analyzed via polar decomposition. It was found that the depolarization properties of fluorescence spectrum from different samples were of significant differences. The depolarization coefficient extracted from the LIF Mueller matrix from diesel varied little with the wavelength increasing, which maintained a high degree of depolarization value within the whole spectral range, while those from other three crude samples kept rising under the same circumstances. With respect to the variation amplitude of the depolarization coefficient, the medium crude sample exceeded the heavy crude but was inferior to the light one. Among the four simulated oil samples, the depolarization coefficient extracted from LIF Mueller matrices from light crude and heavy crude samples were highest and lowest respectively, while those from diesel and medium samples lied between them. Compared to the results of LIF orthogonal polarization experiment under linearly polarized excitation, the depolarization coefficients Delta(lambda) extracted from polar decomposition of LIF Mueller matrices were highly relevant to those DODP obtained from orthogonal polarization characterization of fluorescence spectrum of the simulated oil samples. And it was also found that both the diattenuation and retardation properties of the fluorescence spectrum from the simulated oil samples were very weak and showed little differences.
