Physicists at Stevens Institute of Technology used Christiaan Huygens' 350-year-old theorem, which explains the workings of pendulums and planets, to reveal new properties of light waves. (Courtesy: ...

An experimental technique that started life in nuclear and particle physics is now being used to measure chemical reactions inside the human body and to help diagnose cancer and heart disease in ...

Light fields, as a form of electromagnetic waves, are characterized by fundamental parameters including intensity, phase, and polarization. Precise imaging of these three parameters is crucial for ...

A new publication from Opto-Electronic Science; DOI 10.29026/oes.2022.210009 overviews linear polarization holography. In conventional holography, the hologram is formed by recording the interference ...

A time-resolved x-ray experiment now elucidates that tiny atomic vibrations shift negative charges over a 1000 times larger distance between atoms and switch the macroscopic polarization on a time ...
