摘要
以扩散近似理论为基础，考虑输入超短激光脉冲之后，研究了介质厚度ｄ，吸收系数μａ，散射系数μｓ及各向异性系数ｇ分别对脉冲透射的定量影响。
The most biological tissues are a kind of turbid media. After transmitting through the turbid media, the laser pulse energy will be attenuated and the pulse shape will be changed by scattering and absorption. Besides, the ultrashort laser pulse will be widened by the diffusive scattering. The various medium parameters have different influence on the transmission of the laser pulse. Based on the diffusion approximation theory, this paper researched quantitatively the influence of the thickness d, the absorption coefficient μ a, the scattering coefficient μ s, and the anisotropy coefficient g on the ultrashort laser pulse transmission througt turbid media.
