Even diffuse objects like clouds or sugar cubes cast shadows, because they’re disordered media that scatter light waves. But now, researchers at TU Wien and Utrecht University have found a way to ...

You might expect that an opaque material will always hinder the transmission of light by absorbing or scattering any light that is shone on it. But by carefully preparing a beam of laser light, ...

A transparent substance will allow light to travel through on a straight line, in a turbid substance the light will be scattered numerous times, traveling on more complicated zig-zag trajectories. But ...

A scattering-invariant mode of light is generated by a spatial light modulator. This modulated beam propagates through free space (top) or a strongly scattering medium (bottom) such that the pattern ...

A seemingly paradoxical prediction in physics has now been confirmed in an experiment: No matter whether an object is opaque or transparent, the average length of the light's paths through the object ...
