Laser-Generated Bubbles Create 3D Liquid Images
UTSUNOMIYA, Japan, Feb. 27, 2017 — A volumetric bubble display using lasers allows viewers to see 3D images without 3D glasses or headsets. Researcher, Kota Kumagai of Utsunomiya University in Japan said the new work is currently a proof of concept, but one day might allow full-color updatable volumetric displays. "Creating a full-color updatable volumetric display is challenging because many three-dimensional pixels, or voxels, with different colors have to be formed to make volumetric graphics," said Kumagai.
