To build a mobile holographic video display, the following barriers need to be overcome. It is expected to require quite an amount of time to reach the mobile holographic video for practical applications. However, it has been demonstrated that vertical parallax only holograms using a bulky optical system. The recent study on a holographic display was reported, including a full-colour 3D computer-generated hologram (CGH) calculated in real-time, and a focus-adjustable reconstructed image 10. Many researches have demonstrated holographic video systems so far, including anisotropic leaky mode 8 and eye tracking 9.
4 SIDED HOLOGRAM VIDEO MAKER UPDATE
By using a spatial light modulator (SLM), which directly modulates the wavefront of light, it is possible to update holograms at video rate.
However, those holographic media are non-updatable or have a limited updating frequency 7, causing a fundamental limitation for generating dynamic holograms. Recently, nanophotonics 5 and metasurfaces 6 are also used to reconstruct static holograms. We suggest that the slim-panel holographic display can provide realistic three-dimensional video in office and household environments.īecause of its advantage in 3D image reproduction, the technology for static holograms is quickly developed to a high standard by using hologram recording materials such as silver halide and photopolymer 4. The holographic video processor computes high quality holograms in real-time on a single-chip. The steering-backlight unit enables to expand the viewing angle by 30 times and its diffractive waveguide architecture makes a slim display form-factor. Here we present an interactive slim-panel holographic video display using a steering-backlight unit and a holographic video processor to solve the above issues. However, commercially available holographic video displays have not been introduced yet for several reasons: narrow viewing angle, bulky optics and heavy computing power. at MIT Media Lab developed the first holographic video systems in 1990. Holographic video has been extensively researched for commercialization, since Benton et al. Since its discovery almost 70 years ago, the hologram has been considered to reproduce the most realistic three dimensional images without visual side effects.
