Acoustic Holograms that Levitate Particles

A team of researchers from the Universities of Bristol and Sussex in collaboration with Ultrahaptics have built the world’s first sonic tractor beam that can lift and move objects using sound wave.


Holographic acoustic elements for manipulation of levitated objects by Asier Marzo, Sue Ann Seah, Bruce W. Drinkwater, Deepak Ranjan Sahoo, Benjamin Long and Sriram Subramanian is published in Nature Communications.

Acoustic holograms are projected from a flat surface and contrary to traditional holograms, they exert considerable forces on the objects contained within.

The acoustic holograms can be updated in real-time to translate, rotate and combine levitated particles enabling unprecedented contactless manipulators such as tractor beams.

 
If we talking about the latest holographic techniques then watch this video of an amazing hologram technology show hold in Dubai last year showing spectacular holographic projections of animals, flying dragons and other out of this world creatures.
