Photonics researchers have demonstrated how self-imaging of light, a phenomenon known for nearly two centuries, can be applied to cylindrical systems, facilitating unprecedented control of light's ...

在他们的最新研究成果中，研究人员表明，当光束从一个完全平坦的物体 (如镜子)上反射出来时，其形状会发生轻微变形。虽然这种变形非常小，但却包含了物体本身的重要信息，例如它的材质。这种所谓的拓扑像差效应是英国研究人员十多年前预测到的，现在首次被观测到。

Optics and photonics is the study of the fundamental properties of light and harnessing them in practical applications. Optics and photonics covers the entire electromagnetic spectrum from high ...
