Year 2022 😗😁

For decades we have dreamed of true holographic displays for entertainment, communication, and education. Star Wars had 3D projections rendered in real-time — the definition wasn’t great, but they were communicating across interplanetary distances — and Avatar had holographic maps showcasing the terrain of Pandora. In reality, we mostly have 2D images which show dimension and depth when viewed from different angles. That might be on the verge of changing.

Pierre-Alexandre Blanche from the Wyant College of Optical Sciences at the University of Arizona recently published a paper in Light: Advanced Manufacturing which acts as a roadmap toward true 3D holographic displays.

“3D movies exist already, and the effects are amazing,” Blanche told SYFY WIRE. “But we’re working toward diffraction-based display that will produce all the human visual cues. That’s what’s missing today in the world of 3D display. They’re always missing one or more visual cues.”
