Researchers use laser-generated bubbles to create 3-D images in liquid

Researchers have developed a completely new type of display that creates 3-D images by using a laser to form tiny bubbles inside a liquid ‘screen.’ Instead of rendering a 3-D scene on a flat surface, the display itself is three-dimensional, a property known as volumetric. This allows viewers to see a 3-D image in the columnar display from all angles without any 3-D glasses or headsets.
