Tech News Headline: Japan's 3D laser projector

Japan’s National Institute of Advanced Industrial Science and Technology or AIST has come up with a 3D image projection system that uses precision lasers to project luminous dots in 3D space. The system uses lasers to focus and ignite pockets of nitrogen and oxygen in the air to create plasma emissions that release light. Using very quick bursts of laser light, it can create numerous dots of light to create shapes in 3D space. The system creates a audible crackling noise from the tiny controlled micro-explosions it creates in the air. Future improvements with this technology may yield a wider range of colors as well as extend the distance for projection.
