Researchers at the University of Tokyo have developed a method of using traditional, 2D smartphone screens to create computer-generated ‘holography’.
The approach could revolutionise the development of augmented and virtual
reality displays, using a smartphone screen instead of a laser to create
3D ‘holographic’ images.
The ‘holograms’ are synthesised by solving issues surrounding
the propagation of incoherent light, creating a three-dimensional colour image reproduction
using a two-layered hologram cascade by using an Apple iPhone and a
spatial light modulator, each creating a layer to generate the 3D
image.
Customised algorithms were used to coordinate the display of the
two images to create a 3D ‘holographic’ display that resembles similar images
created by laser systems.
