Chinese researchers develop the largest 3D holographic display

Chinese researchers have created the largest 3D holographic display at 1.8 x 1.3 m². Their invention also includes a way to record and transmit the images. The use 64 digital cameras to capture a 3D object, and the large display uses 64 projectors to re-create the image.

Each projector emits its data onto a holographic functional display screen at various angles. By mirroring the image capture setup, the projectors can recreate the original 3D object. Since the magnification depends only on the ratio between the geometry sizes of projector and camera arrays, the screen size is not limited by the usual restraints experienced by holographic technology. In fact this method can be used to create 3D images in any size, and retain a high-quality image.

The team wants to commercialize this system, but are currently busy optimizing it and developing hardware and software solutions for various applications.
