Researchers at Princeton and Meta have created a tiny optical device that makes holographic images larger and clearer. Small enough to fit on a pair of eyeglasses, the device could enable a new kind of immersive virtual reality display. Illustration by Liz Sabol, photo by Nathan Matsuda
Researchers have invented a new optical element that brings us one step closer to mixing the real and virtual worlds in an ordinary pair of eyeglasses using high-definition 3D holographic images.
Holographic images have real depth because they are three dimensional, whereas monitors merely simulate depth on a 2D screen. Because we see in three dimensions, holographic images could be integrated seamlessly into our normal view of the everyday world.
The result is a virtual and augmented reality disp...
