摘要
本文用后向 Monte- Carlo方法模拟了有水光测量仪器存在的水体中的光场 ,计算了在 L u和Eu测量时仪器阴影误差与仪器在水平面内旋转角的关系 ,仪器倾斜时的辐亮度阴影误差与倾斜角的关系和阴影误差与深度的关系 ,高精度的水光测量在测量过程中和处理数据时应该解决好这个问题。
The backward Monte-Carlo method is utilized to simulate the light field in water where water-optical instrument is presented. The relationships, between instrument shadow error and turning angle on horizontal plane, irradiance shadow error and elevation angle, and the shadow error and depth, are calculated during Lu and Eu measuring, which should be solved carefully in the process of high accuracy water-optical measurement and data treatment.
