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.
