VirtualLab Fusion应用：非近轴衍射分束器的设计与严格分析

摘要直接设计非近轴衍射分束器仍然是一个挑战。由于衍射角相当大，元件的特征尺寸与工作波长在相同的数量级上。因此，设计过程超出了近轴建模方法。因此，在这个例子中，迭代傅里叶变换算法(IFTA)和薄元素近似(TEA)用于衍射元素的初始…...

VirtualLab Fusion应用：用于X射线聚焦的复合折射透镜

摘要单透镜对x射线的折射通常很小，但复合透镜（由数十个或数百个排列成线性阵列的独立柱面透镜组成）可以逐渐聚焦一维或二维x射线。焦距可以通过透镜的数量来控制，即使用的透镜越多，焦距越短。根据Snigirev等人的论文。…...

VirtualLab Fusion应用：立方体分束器中的受抑全内反射

摘要 在光谱分析、干涉测量和光通信领域的许多应用中，分束器设备都发挥着至关重要的作用。一种常见的分束器是基于受抑全内反射（FTIR）：设置第一个玻璃棱镜是为了让入射光线在全内反射条件下照射到其中一个表面，第二个棱…...
