3D display ... a reality soon

Check out this awesome display of 3D images using dots. This could be t he future of true 3D displays. Unlike other displays, this doesn't use any human-eye tricks nor mimic 3D. They display true 3D image in front of you.

From the article:

The AIST, Keio University and Burton Inc., in cooperation, have succeeded in a spatial display of "real 3D images" consisting of dot arrays using a device which is made by additionally incorporating a linear motor system and a high-quality and -brightness infrared pulse laser into the 2D display device mentioned above.

The linear motor system enables the position of the laser focal point to be varied by high-speed scanning of a lens set on the motor orbit. Incorporation of this system makes the image scanning in the direction of the z-axis possible. For scanning in the x and y axis directions, conventional galvanometric mirrors are used.
