用于流体细胞中的高对比度成像的吸收背侧抗反射层
Absorbing Backside Anti-reflecting Layers for high contrast imaging in fluid cells
摘要：
单层增透膜是光学中的一个经典问题。当所有材料都是纯的λ时，溶液就是所谓的λ/4层。在这里，我们研究的情况下，吸收层之间的非吸收介质。我们找到了任何层吸收系数的解决方案，只要光从较高的折射率介质向较低的折射率介质传播，这是背侧层的特征。我们描述这些AR吸收（ARA）层通过广义指数和厚度条件。它们通常是透明的，并且在流体细胞的高对比度成像中具有重要的应用。
英文摘要：
The single Anti-Reflecting (AR) layer is a classical problem in optics. When all materials are pure dielectrics, the solution is the so-called lambda/4 layer. Here we examine the case of absorbing layers between non absorbing media. We find a solution for any layer absorption coefficient provided that the light goes from the higher towards the lower index medium, which characterizes backside layers. We describe these AR absorbing (ARA) layers through generalized index and thickness conditions. They are most often ultrathin, and have important applications for high contrast imaging in fluid cells.
