Using 3-D printing, researchers from the University of Stuttgart built a three-lens camera, and fit it onto the end of an optical fibre the width of two hairs.
Such technology could be used as minimally-intrusive endoscopes for exploring inside the human body, the engineers reported in the journal Nature Photonics.
It could also be deployed in virtually invisible security monitors, or mini-robots with "autonomous vision". Read More Bbarta24.net
