Carbon nanotubes are a man made material thinner than visible light, and they are being used to create holograms.
These tiny tubes are over 100 times stronger than steel and one-sixth the weight. The extremely small size of the tubes, 700 times thinner than a human hair, are the most important aspect of why they are revolutionizing hologram technology. Haider Butt, an optical scientist at the University of Cambridge in England, explains that,
“Due to the nanoscale dimensions of the carbon nanotube array, the image presented a wide field of view and high resolution.”
Scientists are also researching other potential materials that could implement a less static design, creating fluidly changing holograms.
