Over the past few years, physicists and engineers worldwide have developed a growing number of advanced optical technologies and photonic devices, which can be used to emit, detect or manipulate light. The ability to easily ...
A team of researchers at Utrecht University, the Norwegian University of Science and Technology and the University of Konstanz has recently proposed a new method to determine magnon coherence in solid-state devices. Their ...
In conventional holography a photographic film can record the interference pattern of monochromatic light scattered from the object to be imaged with a reference beam of un-scattered light. Scientists can then illuminate ...
(Phys.org)—Physicists have demonstrated that two independently developed concepts—quantum coherence and the nonclassicality of light—both arise from the same underlying resources. The ability to explain seemingly distinct ...
Northwestern University researchers have invented a new high-resolution camera that can see the unseen—including around corners and through scattering media, such as skin, fog or potentially even the human skull.

Optical coherence tomography (OCT) is a light-based imaging technique currently used in clinical diagnostics to examine organs in vivo. The technique uses interferometry; in which light reflected from an examined object combines ...
Specially tailored, ultrafast pulses of light can trigger neurons to fire and could one day help patients with light-sensitive circadian or mood problems, according to a new study in mice at the University of Illinois.
