Offshore oil slicks are significant for both the monitoring of marine spill accidents and the detection of marine oil *** use of remote sensing technology to detect the thickness of oil slicks is a major area of *** reflected light from oil slicks changes with the thickness of the *** is the theoretical basis of research on optical remote sensing of offshore oil slicks.A two-beam interference model that considers the offshore oil slick as a flat plate has been developed in this study.A quantitative remote sensing model which describes a series of processes that use oil slick thickness and reflectance as variables is *** use of the Fresnel equation to analyze parameters in the model indicated that the key property of the quantitative relationship between the oil slick thickness and reflectance was ultimately the disappearance or extinction of the oil *** model has been tested and verified by data from offshore oil slick spectral response *** showed that the oil slick thickness remote sensing model can be theoretically analyzed and is *** research indicated that the major cause of variations in the spectral response as a function of oil slick thickness was the different light-scattering *** characteristics can be used in remote sensing applications to identify the different types of offshore oil *** theoretical interpretation of each parameter in this model led to the development of a look-up table of the model parameters which will improve the efficiency of future offshore oil slick remote sensing.

Inhomogeneity and low efficiency are two important factors that hinder the wide application of laser-induced periodic surface structures. two-beam interference is commonly used to fabricate gratings with interference periods. This study reports regular and uniform periodic ripples fabricated efficiently by the interference of two femtosecond laser beams via a cylindrical lens. The interference period is adjusted to be an integer multiple of the wavelength of a surface plasmon polariton. Regular and uniform subwavelength nanogratings(RUSNGs)on a silicon wafer of a diameter of 100 mm are fabricated with a scanning velocity of 6–9 mm/s. Bright and pure colors(including purple, blue, and red) are demonstrated on different patterns covered with RUSNGs.
