| 摘 要： | 对基于漫射理论并应用CCD相机测量混沌介质的光学常数进行了实验研究.提出采用漫射中心环带约束法来提高逆向求解光学常数的精确性,以及采用在通过光的入射点和漫射中心的直线上截取一维原始数据的方法来提高算法的计算效率.以Intralipid脂肪乳剂作为混沌介质,对方法进行了实验验证.结果表明,本文提出的方法是可行的.

| Abstract: | Measurements of optical parameters of turbid media based on diffusion theory with CCD camera are studied experimentally.The method of zone restriction for the purpose of deterinating diffused reflectance center is proposed in order to improve the precision of optical parameters.In addition,the method of obtaining one-dimensional data from the line through incident point of light and diffused reflectance center is proposed so as to increase the efficiency of inverse algorithm.Intralipid is used to verify the... |
