摘要 平均余弦是海水重要的表观光学参数之一。本文分析比较不同水质参数下平均余弦随散射次数以及传输距离的变化规律,得出准直光束在不同水质海水中散射次数的分布及极限。 The average cosine is one of the most important apparent optical properties of the ocean, because it provides information about the angular structure of the light field. This paper analyzes and calculate the average cosine in different scattering times and different distances the photons passed, getting the limit scattering times that photons experience in different optical properties of the ocean.
