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。
The time-domain reflection and transmission signals obtained by the finite volume method (FVM) when the laser is incident on the translucent medium are combined with three different intelligent algorithms (PSO, SPSO and MPPSO) The inversion of the absorption coefficient and the scattering coefficient of the isotropic scattering homogeneous medium under the irradiation of short pulse laser show that all the three particle swarm optimization algorithms can efficiently and accurately retrieve the optical parameters of the homogeneous medium.
