PARIS – German engineers have created a camera no bigger than a grain of salt that could change the future of health imaging — and clandestine surveillance.
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. Continue reading “Micro-camera can be injected with a syringe”
