Three-Dimensional Images Are Conjured in a Crystal Cube

Summary

Engineers have long struggled to build displays that create the illusion of three dimensions. A Research Article on page 1185 reports something that may be better than illusions: true 3D images, traced within a cube of special glass by a pair of lasers. The lasers deliver invisible infrared light; where their beams cross, they create a point of fluorescence. The prototype display is small and its information content is low, but some researchers think full-fledged versions could have applications in everything from medicine to air-traffic control.
