Diffraction is a fundamental wave phenomenon. It manifests itself for light waves in almost all optical systems, limiting our ability to focus or collimate light beams. Due to diffraction, it is ...

Light diffraction and interference are investigated. Unit 6 Segment H: Light: Diffraction and Interference Light diffraction and interference are investigated as we observe light going through single ...

Two become one: various diffraction patterns showing Rayleigh's criterion. (Credit: Wikimedia Commons/Spencer Blevin) Scientists have long believed that diffraction limits the minimum distance that ...

Increasingly complex applications such as artificial intelligence require ever more powerful and power-hungry computers to run. Optical computing is a proposed solution to increase speed and power ...

Researchers at Harvard University and Jiangsu University developed a technique for not only identifying infected cells, but also tracking the infection over time as the cells developed. They published ...
