Holography is a technique that is used to display objects or scenes in three dimensions. Such three-dimensional (3D) images, or holograms, can be seen with the unassisted eye and are very similar to how humans see the actual environment surrounding them. The concept of 3D telepresence, a real-time dynamic hologram depicting a scene occurring in a different location, has attracted considerable public interest since it was depicted in the original Star Wars film in 1977. However, the lack of… 
Digital holographic display
This paper describes how a Digital Holographic Projector is designed and implemented to project two-dimension virtual images onto the volumetric display media. In this research, we focus on the
Holographic Printing of White-Light Viewable Holograms and Stereograms
The holographic printing followed the two main approaches in this area: i) computation of the holographic fringes by numerical simulation of the interference and encoding the resulting pattern onto a suitable medium for further optical display.

Volume holography using gold-nanoparticle-doped photopolymers for 3D display
Although we view the physical world around us in 3D, traditional displays show only 2D images lacking depth information. The development of 3D display technologies would enormously benefit many
