A broad range of optical devices use nanostructured layers and surfaces to manipulate beams of light through diffraction and interference. Example devices include diffraction gratings, metasurfaces, ...

Advancements in structured illumination and computational imaging are revolutionizing semiconductor wafer inspection, ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

1.The concept and principle of optical reticle. The optical reticle, also known as an optical grating or grating plate, is an optical element with a periodic structure, usually made of a transparent ...
