Laser-Generated Bubbles Create 3D Liquid Images

Facebook X LinkedIn Email
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. "In our display, the microbubble voxels are three-dimensionally generated in a liquid using focused...Read full article
