WiMi to Develop HoloBrick Unit Display System for Powerful Holographic 3D Display

WiMi Hologram Cloud, a leading global Hologram Augmented Reality (“AR”) Technology provider, today announced that it is developing a HoloBrick unit display system. The unit is based on coarse integrated holographic displays for corner-tiled 3D images stitched together to form a giant, seamless 3D image. Each holographic brick uses a high information bandwidth spatial light modulation device to transmit information and coarse integrated optics to create a large viewing angle and field of view angled tiled 3D hologram.

The system allows seamless spatial tiling of multiple CIH displays. The HoloBrick is an independent CIH module containing a spatial light modulator, scanner, and periscope coarse integration optics. The periscope coarse integral optics are created to prevent the optical system from being more significant than the holographic image and allow the holographic stripe pattern to fill the entire surface of the HoloBrick. As a result, multiple HoloBricks can be seamlessly connected to form a scalable spatially tiled hologram display capable of both a wide field of view and an arbitrarily large size area. The optical design enables each of the resulting holograms to fuse the displayed 3D images in space when seamlessly stitched together.

Diffractive optics causes the holographic effect. Its scattering angle depends on its wavelength and the size of the diffracted material. The 3D effect can be rendered by moving the object slightly, but the object cannot be seen if the angle is too large. The CIH module can solve this problem by adjusting each angle in space to about two degrees for spatial stitching, thus obtaining a spatial field of view of 30-40 degrees or more. The modular CIH in the system uses coarse pitch and small area but high bandwidth SLMs combined with periscope coarse integration optics to form angularly tiled stereoscopic 3D holograms with large fields of view and field of view.

WiMi will continue to develop the ultimate display technology that connects the real world with the virtual world, reconstructing high-quality images for an immersive experience.
