摘要
为实现利用采用紫外波段对海水溢油污染进行监测, 采用了回转半径为1 500 mm的双向反射分布函数测量装置和工作波段为300~400 nm的大视场紫外成像仪, 对海水溢油紫外反射光谱特性进行研究.对三种油样品进行了外场试验, 试验结果表明: 海水溢油紫外光谱双向反射分布函数测量装置不确定度为3.68%; 在天顶角0°和30°, 相对太阳方位角0°和45°时, 原油样品与海水的双向反射分布函数在紫外波段差别较大.因此, 可利用此状态下300~380 nm工作波段的紫外光学遥感仪器监测海水溢油状态.
Abstract
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.
