论文摘要
异常辐射转移（ART）理论是经典辐射转移理论的概括。本教程希望展示如何实施描述异常介质中光子传输的蒙特卡洛（MC）代码。结果表明，该方法的核心包括以“非古典”方式适当地描述从固定光源开始的光子步骤，或从分离具有不同光学特性的介质区域的边界开始。为了更好地直觉这些特定光子步长的长度的重要性，也从数值上表明，所述方法对于保留光传播的不变性属性至关重要。 MC ART方法的一个有趣的副产品是，它使我们能够简化“经典” MC代码的结构，例如在生物医学光学元件中。
Anomalous radiative transfer (ART) theory is a generalization of classical radiative transfer theory. The present tutorial wants to show how Monte Carlo (MC) codes describing photons transport in anomalous media can be implemented. It is shown that the heart of the method consists in suitably describing, in a "non-classical" manner, photons steps starting from fixed light sources or from boundaries separating regions of the medium with different optical properties. To give a better intuition of the importance of these particular photon step lengths, it is also shown numerically that the described approach is essential to preserve the invariance property for light propagation. An interesting byproduct of the MC method for ART, is that it allow us to simplify the structure of "classical" MC codes, utilized e.g. in biomedical optics.
