摘　　要：为了对光在生物组织中的传播特性有更多的了解,分析了发散光束在介质中的传播情况。利用VC++语言编制了一套发散光束在半无限大生物组织内传播的Monte Carlo模拟程序,对几种不同参数值的情况进行了模拟。通过对模拟结果的分析,得出了发散光束在半无限大生物组织内传播的规律,为发散光束在光诊疗中的应用提供了参考。In order to study the light propagation in biological tissue, we analyzed the divergent beam propagation in turbid medium. We set up a Monte Carlo simulation model for simulating the divergent beam propagation in a semi- infinite bio-tissue. Using this model, we studied the absorbed photon density with different tissue parameters in the case of a divergent beam injecting the tissue. The simulation results showed that the rules of optical propagation in the tissue were found and further the results also suggested that the diagnosis and treatment of the light could refer to the rules of optical propagation.
