In order to monitor the marine oil spill state used ultraviolet band, the Bi-Directional Reflectance Distribution Function (BRDF) measurement device which the turning radius is 1500mm and the large field of view ultraviolet imager which the working band is from 300nm to 400nm are used to study the spectral characteristics of oil spill ultraviolet reflection. The datas are measured by three kinds of oil samples through the field test, the results is showed that the uncertainty of the ultraviolet reflectance distribution function measurement device is 3.68%; There is different between the oil samples target and sea water BRDF in the ultraviolet wave range under the condition of the zenith angle of 0° and 30° degrees, relative azimuth angle of 0° and 45°. So the conclusion can be usedto monitormarine oil spill stateswiththe ultraviolet optical remote sensor from 300 nm to 380nm band.
