Butterfly Wing Optics Help to Cheaply Create Bright, Realistic Holograms

Researchers used complex 3D nanostructures to produce holograms with the rich colors and bright display that may one day make sophisticated holograms an everyday reality.

University of Utah electrical and computer engineering associate professor Rajesh Menon shows off a new 2D hologram that can be displayed with just a flashlight. His team has discovered a way to create inexpensive full-color 2D and 3D holograms that are far more realistic, brighter, and can be viewed at wider angles than current holograms. | Dan Hixson/University of Utah College of Engineering
