摘要 利用激光入射半透明介质时有限体积法(FVM)得到的时域反射和透射信号,结合标准微粒群(PSO)、随机微粒群(SPSO)和多相微粒群(MPPSO)三种不同的智能算法反演短脉冲激光辐照下各项同性散射均匀参与性介质的吸收系数和散射系数,结果表明三种微粒群算法都能够高效准确地反演均匀介质内的光学参数。 In this paper the time domain transmittance and reflectance signals calculated by FVM solving transient radiative transfer equation（RTE） and the three intelligent methods PSO.SPSO or MPPSO have been used to inverse the absorption and scattering coefficient of isotropic uniform media.The results show that these three methods can reconstruct the messages of optical parameter efficiently and correctly for the isotropic homogenous media.
