Researchers have created a two-layer optical reproduction of a full-color 3D image by displaying one holographic layer on the screen of an iPhone 14 Pro and a second layer on a spatial light modulator. The resulting image measured a few millimeters on each side.
They are now working to improve the technology so that it can display larger 3D images with more layers. Additional layers would make images look more realistic by improving spatial resolution and allowing objects to appear at several different depths, or distances, from the viewer.
