摘要
近年来,海洋资源开发、海洋自然环境保护以及海洋军事应用等方面的研究越来越引起人们的关注。光电探测成像技术是海洋探测及环境保护的重要手段之一,分析强散射背景条件水下光场传输特性是光电探测成像的基础。基于蒙特卡罗方法仿真分析了在强散射背景条件下水体的光传输规律,并得到了水体中光场空间分布规律和透射光通量空间分布规律,进一步对比分析了不同深度水体下,散射光子和弹道光子对探测光的影响。
In recent years,researches on marine resources exploitation,marine natural environment protection and marine military application have attracted more and more attention.Photoelectric detection and imaging technology is one of the important means of ocean detection and environmental protection.It is the basis of photoelectric detection imaging when analyzing the transmis⁃sion characteristics of underwater light field under strong scattering background condition.In this paper,Monte Carlo method is used to simulate and analyze the law of light transmission in water under the condition of strong scattering background,and the spa⁃tial distribution of light field in water and the spatial distribution of transmitted luminous flux are obtained.Furthermore,the effects of scattered photons and ballistic photons on detecting light under different water depths are compared and analyzed.
