Researchers developed a novel tunable ultrasonic liquid crystal light diffuser that allows changing the diffusion direction It is no mystery that light is essential to human life. Since the discovery ...

I am a macro photographer who takes photographs mainly using a flash to illuminate my subject. In this line of photography as with most the quality of your light is key to the quality of your ...

Researchers developed a nanostructured light diffuser that provides balanced lighting by diffracting blue and red light, and can be cleaned by simple rinsing with water. The diffuser consists of cheap ...

Watch Visual Effects artist Joe Letteri explain how the science of light diffusion made digital characters more realistic. It was near midnight in the winter of 1998 when computer graphics researcher ...

The interplay between light and hand-held device screens has driven research into light-diffusing materials that obviate such undesired aspects as image blur. As the field continues to expand, the ...

Levy flights in an optical material were observed by a team of scientists for the first time in May this year. Marie Freebody speaks to Diederik Wiersma, the man at the head of the group, to find out ...

From astronomy to cell biology, the manner in which light propagates in turbid media has been of central importance for many decades. However, light propagation near the point-of-entry in turbid media ...

Researchers have just discovered a new type of light diffusion in tiny optical fibers 50 times thinner than a strand of hair. This phenomenon, which varies according to the fiber's environment, could ...

Future iPhone cameras may contain a flash that automatically adjusts and diffuses its light to better capture objects at different distances from the lens. If camera flashes were better, Apple might ...
