New Technology Uses Light to Engrave Erasable 3D Images

Imagine if physicians could capture 3D projections of medical scans, suspending them inside an acrylic cube to create a hand-held reproduction of a patient’s heart, brain, kidneys, or other organs. Then, when the visit is done, a quick blast of heat erases the projection, and the cube is ready for the next scan. A new report by researchers at Dartmouth and Southern Methodist University outlines a technical breakthrough that could enable such scenarios, and others, with widespread utility.

Seeing Like a Butterfly: Optical Invention Enhances Camera Capabilities

Butterflies can see more of the world than humans, including more colors and the field oscillation direction, or polarization, of light. Other species, like the mantis shrimp, can sense an even wider spectrum of light, as well as the circular polarization, or spinning states, of light waves. Inspired by these abilities in the animal kingdom, researchers have developed an ultrathin optical element known as a metasurface, which can attach to a conventional camera and encode the spectral and polarization data of images captured in a snapshot or video through tiny, antenna-like nano-structures that tailor light properties.
