Three-Dimensional Images in Midair

3D displays that hover in midair have been a staple of science fiction for decades; after all, who can forget the hologram of Princess Leia in the first Star Wars? Now, Japan's National Institute of Advanced Industrial Science and Technology (AIST) has developed a method of projecting three-dimensional images in the air.

The system reflects laser light off of mirrors, and focuses that light into a point in the air using a plasma emission phenomenon.

The technology remains experimental, so there is no estimate of when it might appear in the marketplace.
