基于麦克斯韦方程组的 OCT 成像系统的“全波”模型开始成为成熟近似模型的可行替代方案。然而，在处理大样本时，这些模型的计算量很大。在这里，为了减少计算负担，我们提出了一种仅使用入射在给定样本介质上的平面波的单一模拟来合成全波扫描模式 OCT 图像形成的方法。该方法涉及角谱方法，该方法合成任意扫描位置和任意照明条件的信号。与之前需要对每个扫描位置进行单独模拟的方法相比，这已被证明可以将合成 OCT B 扫描时所需的模拟时间减少一个数量级。
“Full-wave” models of OCT imaging systems based on Maxwell’s Equations are beginning to emerge as feasible alternatives to well established approximate models. These models are however computationally taxing when dealing with large samples. Here, in an effort to reduce the computational burden, we present a means of synthesizing full-wave scanning-mode OCT image formation using only a single simulation of a plane wave incident on a given sample medium. The method involves an angular spectrum approach which synthesizes the signal for arbitrary scan positions, and arbitrary illumination conditions. This is demonstrated to reduce the required simulation time by an order of magnitude when synthesizing OCT B-scans, as compared to previous methods which require a separate simulation for each scan position.
