Fairy Lights Holography: Japanese Researchers Develop a Safe Open-Air Interactive Hologram

A research team from Tsukuba University in Japan has announced their development of an apparatus that is capable of projecting open-air holograms that are safe for humans to interact with.

While the practice of modern holography was invented in 1962, the holograms produced were imprinted on clear glass or plastic sheets, and required the viewer to look through that medium to view the holographic image itself. Open-air holography methods using fast-pulsing lasers have been developed in recent years, but the images themselves were hazardous, as the plasma generated in the air to produce the image was hot enough to burn human skin.
