(Phys.org)—There are many different ways to generate a hologram, each with its own advantages and disadvantages. Trying to maximize the advantages, researchers in a new study have designed a hologram made of a metamaterial consisting of aluminum nanorods that can produce light across the entire visible spectrum, and do so in a way that yields brighter images than other methods.
