Light trick to see around corners (BBC) {or through scattering materials}

[eppur_se_muova]

Scientists have found a novel way to get images through "scattering" materials such as frosted glass or even skin, or even "see around corners".

Much research in recent years has focused on correcting for scattering, mostly for medical applications.

But the new trick, reported in Nature Photonics, is quick, simple and uses natural light rather than lasers.

It uses what is called a spatial light modulator to "undo" the scattering that makes objects opaque or non-reflecting.

A camera that can "see around corners" garnered much attention in 2010, using a series of timed laser pulses to illuminate a scene and working out what is around a corner from the timing of the reflections.

1. Wow

I can think of a few sinister applications for this...think TSA..interesting medical applications..one of the puzzle pieces of the unknown which incites a spirit of pioneering..
