摘　　要：为了定量研究泡沫对激光传输的影响，基于电波吸收、反射和散射特性对泡沫衰减遮蔽机理进行了分析。根据泡沫状态的不同，将泡沫分为离散泡沫和粘连泡沫，运用朗勃一比尔定律定量计算了离散泡沫的激光透过率及能量衰减值，运用几何光学和电磁波传播理论定量计算了粘连泡沫的激光透过率及能量衰减值，并利用MATLAB中仿真工具进行了数值仿真。结果表明，泡沫对激光衰减作用明显，且随着泡沫厚度的增加，激光透过率逐渐减小，与测得的实验值基本一致，进一步验证了模型的合理性。
In order to study effect of foam on laser transmission quantitatively, based on the absorption, reflection and scattering characteristics of electromagnetic wave, attenuation blanking mechanism of foam was analyzed. According to different foam condition, foam was divided into discrete foam and adhesive foam, and their transmission and energy attenuation were calculated quantitatively with Lamber-Beer law and theories of geometrical optics and electromagnetic wave propagation. The numerical simulation results based on MATLAB tool show that foam has obvious effect on laser attenuation, with increasing of foam thickness the transmission of laser is diminishing, and it is similar to experimental. The rationality of the model is proved further.
