Holograms in the Classroom?

Update: Ars Technica has a good article on it here.

Wow. I tend to be an optimist about technology and where it will go but this one caught me off guard.  Apparently a team at University of Arizona has come up with a way to make true 3d holograms.  These are free floating 3d objects made of light.  This is just amazing!  (Like in Star Wars where they had holograms of people)

The time-line for this technology is 7-10 years they say.  That’s really fast.

The implications for the classroom are huge.  This takes teleconferencing to a whole new level. Imagine being able to have a guest lecturer come into your classroom without actually being there.  Or how about setting up a room like a Holodeck from Star Trek where 3d objects can be created around you? Of course you can’t actually touch these things but still it’s quite amazing.

This technology is just another cloud in the Stormfront on the horizon. 🙂 Awesome!

  • Amazing technology for true 3d holograms

    • The scientists at the University of Arizona say their prototype “holographic three-dimensional telepresence” is the world’s first practical 3D transmission system that works without requiring viewers to wear special glasses or other devices. The research is published in the journal Nature.
    • “Holographic telepresence means we can record a three-dimensional image in one location and show it in another location, in real-time, anywhere in the world,” said Nasser Peyghambarian, project leader.
    • The heart of the system is a new “photographic” polymer developed by the California research labs of Nitto Denko, the Japanese electronic materials company.
    • A 3D image is recorded with an array of cameras, capturing the object from different positions, and is then encoded digitally in a fast-pulsed laser beam, which creates holographic pixels or “hogels” in the polymer. The image itself results from an optical interference pattern between two laser beams.
    • Professor Peyghambarian said it would take at least seven to 10 years’ work before a consumer version of the system was ready to test in people’s homes.

  1. I am researching this and am already planning lessons around the use of these holograms. My goal is to help develop information to help this research. Could you help me?

    • Hey Fritz!

      That is very forward thinking of you! I usually store any stories like this on Diigo. Keep an eye on this Diigo stream and you will see anything I come up with.

      Good luck and thank for commenting!
