Fingernail-sized, gemstone-shaped, it's the first device of its kind.
Researchers at Ohio State University have a made a lens that simultaneously takes pictures of an object from nine angles, images which are then combined to make a 3-D one. The lens, informs The Engineer, "is claimed to be the first single, stationery lens to create microscopic 3D images by itself."
The lens, roughly the size of a fingernail, is currently in prototype, and looks like a gemstone with eight facets. Lei Li, an Osu postdoc, wrote a program to cut a tiny piece of acrylic glass using an ultraprecision milling device. The facets vary in size and angle, in such a way that an object placed underneath is viewed from multiple angles at once. It's "basically like putting several microscopes into one," said Li in a release.
