[Translate to chinese:] Video Talk by Kurt Thorn: The Abbe Diffraction Experiment

Kurt Thorn的视频讲座：阿贝衍射实验

本讲座介绍了恩斯特-阿贝的著名实验，该实验显示了试样对光线的衍射（以及与照明光线的干涉）是如何产生图像的，以及衍射光线的收集是如何定义显微镜的分辨率的。这些概念是通过使用衍射光栅作为样本，以及可视化和比较后焦平面的衍射图案以及图像平面的图像来展示的。

什么是OCT？

光学相干断层扫描（OCT）是一种无创、非接触式成像方式，可用于显示并监测生物组织的形态变化。OCT利用低相干干涉原理，可生成横断面视图，以揭示感兴趣组织的亚表面细节。在大部分常见眼科应用中，OCT系统通过近红外光生成角膜、虹膜、晶状体、玻璃体和视网膜等组织微结构的高分辨率体积图像。这些图像可加强对病理状况的理解，例如青光眼、老年性黄斑变性或糖尿病视网膜病变。

选择学生显微镜需要考虑的因素

对于教师来说，选择教育显微镜并非易事。显微镜必须经得起并非总是小心翼翼的双手的日常使用，必须能够持续运行，还必须符合预算要求。尤其是学生用显微镜，实用性方面起着重要作用： 尺寸、重量、布线和设计在日常使用中非常重要，甚至在决定使用显微镜的设备和附件之前就应考虑到这一点。如果选择得当，教育显微镜将为大中小学的年轻人打开一扇通往微小细节的宇宙之窗，让他们对科学产生足够的兴趣，并将其作为自己的职业。
