Numerical Simulation of Radiative Transfer

A maximum a posteriori (MAP) estimation based on Bayesian framework is applied to image reconstruction of two-dimensional highly scattering inhomogeneous medium, and the finite difference method and conjugate gradient algorithm are served as the forward and inverse solving schemes; the standard particle swarm optimization, the stochastic particle swarm optimization, and the hybrid differential evolution-particle swarm optimization are applied to solve the inverse transient radiation problem in 2D turbid media irradiated by the short pulse laser, and the time-resolved radiative signals simulated by finite volume method are regarded as input data for the inverse analysis.
