The holobrick proof-of-concept can tile holograms together to form a large seamless 3D image.
A 2D full HD display needs an information data rate of about three gigabits per second, but a 3D display of the same resolution would require a rate of three terabits per second, which is not yet available.
“Delivering an adequate 3D experience using the current technology is a huge challenge,” said Professor Daping Chu from Cambridge’s Department of Engineering, who led the research.
“Over the past ten years, we’ve been working with our industrial partners to develop holographic displays which allow the simultaneous realisation of large size and large field-of-view, which needs to be matched with a hologram with a large optical information content.”
