Simulation of optical coherence tomography using Monte Carlo method
光学相干层析信号的模拟分析与计算

The new assumption that a photon cannot be split is made in the Monte Carlo simulation for optical scattering response function is made,which eliminates the uncertainly in arbitrarily choosing the threshold of photon death.A hyperbolic method is proposed to simulate the Gaussian beam used in optical coherence tomography systems where curved sample interfaces are encountered.Comparison between the calculated OCT pictures of a microscope slide(flat interface)and a cornea(curved interface)with the corresponding experimental ones indicates the effectiveness and the relative advantage of our new simulation method.
