Holograms can produce strikingly realistic three-dimensional images from light hitting a two-dimensional surface. Aside from some applications as counterfeit-resistant security images used on currency, holograms have mostly remained a novelty. But now researchers are hoping to move holograms out of the realm of museum exhibits and take advantage of their ability to store large amounts of data. A new study demonstrates a gold nanorod material that serves as a . . .
