Physicists create Star Wars-style 3D projections — just don’t call them holograms — SCI- TECH

 

They may not technically be holograms, but they're pretty impressive: Researchers have created moving 3D images that are viewable from any angle. The technique, called volumetric display, comes from the lab of Daniel Smalley at Brigham Young University. Smalley's team uses two sets of lasers—one traps and moves a particle around, while the other projects color onto the particle. The particle moves so quickly that our eyes perceive the projection as a solid-line image.
