摘要
偏振态与散射次数的关系对于提取深入组织内部的后向散射光有很重要的价值.本文分析了透射光的偏振度与光在介质中的散射次数的关系,给出了偏振光完全失去偏振态所需的散射次数,并用直接散射的实验方法进行了验证,得出当散射次数为14次时偏振光将失去其偏振特性的结论.
The relationship of polarizability and scattering number has great value to extract the backscattering light deeply into the tissue. The relationship of polarizability of transmitted light and the scattering number of light in medium is analyzed. The scattering number that purely depolarization needed is given. And the result is validated by directly scattering experiment. The conclusion can be made that when the scattering number is 14, the polarization light will be depolarized.
