Fluorescent bubbles inside a liquid display could be the next big thing in 3D technology, allowing viewers to walk around the "screen" without using any special glasses, scientists say.
Technology for 3D images has relied on glasses or headsets for users to experience the dimensions of an image rendered on a flat surface. Now, however, a team of researchers has published a proof of concept for a display that projects 3D images in a way that makes them visible from all angles and, as such, does not require the eye accessories.
The team's new technique uses lasers to create bubbles in a thick liquid. Then, the bubbles are illuminated using a lamp. These colorful bubbles act as voxels (3D pixels), creating three-dimensional images in the fluid "screen," which itself is three-dimensional, or volumetric.
