A team of researchers with the University of Stuttgart has used advanced 3D printing technology to create an extremely small camera that uses foveated imaging to mimic natural eagle vision. In their paper published in the journal Science Advances, the group describes their approach to creating a small high-resolution camera and possible applications.

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 3D 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 t...
