There is no current technology to project a real life-sized, moving, talking hologram in a public place that permits a person to walk all the way around and view it from all sides. The virtual 3D world where you can project anything you want into thin air like The HoloDeck of Star Trek fame is still a long way off. By harnessing the unique capabilities of laser light, Holography and other optical technologies Laser Magic has developed several real-time technologies to project images into 3D space. These technologies are patented, patent pending or proprietary to Laser Magic. Each of these technologies is capable of creating the illusion of an image suspended in space.
Some methods permit movement of the image.
With some you can even walk up to and put your hand through the image. Each technology is appropriate for some applications but not for others. For example if you want to see a life-sized ghostly image moving around on stage, the method of choice would be 2D image projection onto a moving transparent screen. To generate a real 3D image floating in space with actual depth you would use stereo 3D projection onto our TransScreen along with polarized 3D glasses.
