Heading toward a 3-D World

Article excerpt

A research team has created the world's thinnest hologram, paving the way toward the integration of 3-D holography into everyday electronics such as smart phones, computers, and TVs.

The challenge for scientists trying to turn interactive 3-D holograms into reality is developing holograms that are thin enough to work with modern electronics. Now, a research team has designed a nano hologram that is simple to make, can be seen without 3-D goggles, and is 1,000 times thinner than a human hair.

"Conventional computer-generated holograms are too big for electronic devices but our ultrathin hologram overcomes those size barriers," says RMIT distinguished professor Min Gu. "Our nano hologram is also fabricated using a simple and fast direct laser writing system, which makes our design suitable for large-scale uses and mass manufacture."

Screen size would be irrelevant when holography becomes integrated into everyday electronics. Three-dimensional holography could also transform a number of industries, including medical diagnostics, data storage, defense and cyber security, Gu says. …
