A fibre-optic cable the thickness of a human hair can transmit accurate 3D images in real time, creating a tiny flexible camera.

Miles Padgett at the University of Glasgow, UK, and his colleagues are suffering from something several orders of magnitude smaller than pre-existing cameras predicated on fibre-optic cable.
