Outdoor Marketing: 3D Images By Laser
Japan’s National Institute of Advanced Industrial Science and Technology (AIST) has developed a device that uses lasers to project real three-dimensional images in mid-air.
The institute unveiled the device on February 7 in a demonstration that showed off the device’s ability to project three-dimensional shapes of white light.
The newly developed device, however, creates 3D images by using laser light, which is focused through a lens at points in space above the device, to create plasma emissions from the nitrogen and oxygen in the air at the point of focus. Because plasma emission continues for a short period of time, the device is able to create 3D images by moving the point of focus. More info at the Pink Tentacle:
