About 3D Holographic Projection Technology

3D holographic projection technology is basically based on an illusionary technique that is called Peppers Ghost and in the 1860s it was first used in Victorian theatres across London. The pepper’s ghost was usually used to great effect in theatres and create ghost-like figures on stage.

Hidden from audience’s view, the actors dressed up in ghostly clothes would stand facing an angled plate of the glass. All audience would be able to see a glass but not that actors directly. Particularly angled lighting would reflect an actor’s image into the plate of glass and a transparent ghost-like reflection would appear in the front of an audience.

How is this 3d hologram technology used today?

With the use of the latest CGI animation, expert HD film techniques, HD projectors and unique effects created in the post-production, this Pepper’s Ghost technology has been updated to the 21st century. Instead of real object or person’s reflection appearing on the plate of glass, high definition video and CGI animation are beamed directly onto uniquely designed, chemically treated transparent film through the high power HD projector. While much more expensive, this latest approach results in a much clearer, credible hologram projection.

What type of images can be projected as holograms?

Due to the latest approach of projecting CGI animations and pre-recorded footage, almost everything is possible. The blank canvas approach is usually adopted, creating a storyboard simply limited by an imagination. The storyboard can then be handed over to the CGI animation team who can make it come to life using a latest 3d holographic display.

Real characters can be filmed giving a speech, performing dance or presentation for example and then be projected as 3D holograms. Holographic special effects can be combined in the post-production to make a life-like person beam into a room or have their product appear above their head at a click of their fingers.
