Holographic prototype enables mid air displays
A 3D hologram start up firm has launched a new holographic display that has dynamic moving images, paving the way for next generation static printed holograms for scientific, medical and engineering visualisation applications.
According to Edinburgh based Holoxica, the idea is to expose a series of holograms on a single sheet that is rear illuminated by a laser projector. While similar multi-exposure holograms have been demonstrated before, showing different views of the scene as the viewer moves from side to side, Holoxia's views are all visible from a stationary viewing position. And, adds the company, the views can be turned on and off with electronic control, creating a series of 'flip card' images that appear to float in front of the A4 sized screen. ...
"The 'mid air suspension' holographic screen currently embeds up to nine images, but this number can be scaled up," said Javid Khan, managing director of Holoxica. "Indeed, we can scale up toward 25 images, where it is possible to get a second of full 3D video or make other kinds of animated characters. Although colour is limited at the moment, the plan is to extend this in the future to give full colour images by combining red, green and blue light sources." ...
