    Digitized holography techniques are used to reconstruct three-dimensional (3D) images of physical objects using large-scale computer-generated holograms (CGHs). The object field is captured at three wavelengths over a wide area at high densities. Synthetic aperture techniques using single sensors are used for image capture in phase-shifting digital holography. The captured object field is incorporated into a virtual 3D scene that includes nonphysical objects, e.g., polygon-meshed CG models. The synthetic object field is optically reconstructed as a large-scale full-color CGH using red-green-blue color filters. The CGH has a wide full-parallax viewing zone and reconstructs a deep 3D scene with natural motion parallax.

  • Rendering of specular curved objects in polygon-based computer holography Reviewed

    Language:English   Publishing type:Research paper (scientific journal)   Publisher:OPTICAL SOC AMER  

    A realistic rendering technique is presented for creating large-scale computer-generated holograms. The technique is based on the polygon-based method, but allows specular curved surfaces to be reconstructed without increasing the number of polygons. In this technique, specular flat surfaces are transformed into curved surfaces. This is achieved by controlling the direction of reflected light, using fragmentary plane waves. An actual large-scale computer-generated hologram is created, and is used to verify the validity and practicality of the technique. (C) 2017 Optical Society of America

    A technique using RGB color filters is proposed for creating high-quality full-color computer-generated holograms (CGHs). The fringe of these CGHs is composed of more than a billion pixels. The CGHs reconstruct full-parallax three-dimensional color images with a deep sensation of depth caused by natural motion parallax. The simulation technique as well as the principle and challenges of high-quality full-color reconstruction are presented to address the design of filter properties suitable for large-scaled CGHs. Optical reconstructions of actual fabricated full-color CGHs are demonstrated in order to verify the proposed techniques.

  • Silhouette method for hidden surface removal in computer holography and its acceleration using the switch-back technique Reviewed

    A powerful technique is presented for occlusion processing in computer holography. The technique offers an improvement on the conventional silhouette method, which is a general wave optics-based occlusion processing method. The proposed technique dramatically reduces the computation time required for computer-generated holograms (CGH) of self-occluded objects. Performance measurements show that a full-parallax high-definition CGH composed of billions of pixels and a small CGH intended to be reconstructed in electro-holography can be computed in only 1.7 h and 4.5 s, respectively, without any hardware acceleration. Optical reconstruction of the high-definition CGH shows natural and continuous motion parallax in the self-occluded object. (C) 2014 Optical Society of America

    Computer holography is a technique that makes it possible to create the ultimate 3D image reconstructing stunningly deep 3D scenes. This research project mainly focusses on the techniques to create and reconstruct full-color 3D images in this computer holography, and, in addition, developed various related techniques. In particular, we developed a novel technique, called ‘Stacked CGVH’, for producing full-color holograms and confirmed that the technique reconstructed much better 3D images than those based on the conventional RGB color filters technique. Furthermore, to remove obstructive light that disturbs view of 3D images, several other techniques such as phase modulation, fringe oversampling techniques, and a back-light system for illumination were developed in the project. Techniques developed through the project allow us to create 3D images that are easy to view and have high quality in computer holography.

    A novel technique for full-color computer-generated holograms (CGH) is developed for actual exhibition of full-color 3D images. In this technique, RGB color filters are attached closely to a fringe pattern printed by laser lithography. Since the fringe pattern behind the RGB color filters is generated at a wavelength corresponding to the RGB color, viewers can see a full-color 3D image without any severe color smear. In addition, application software is developed for non-experts of computer holography to design and calculate full-color CGHs. The technique of full-color digitized holography is also developed to make full-color CGHs that reconstruct a 3D scene including physical real-existing objects as well as CG-modeled virtual objects. In this technique, the object field of a subject is recorded at three wavelengths using synthetic aperture digital holography.

    We are developing the fabrication technology of hologram optical elements which is possible about the reconstruction of the true three-dimensional image. In the holography technology, a computer hologram is obtained. Using a laser lithography system, the pattern of the computed interference fringe is exposed directly on the photomask substrate. We are able to fabricate holograms by exposing a computed fringe pattern by the lithography system and etching to the chromium thin film after developing of photoresist. For wide view area, we used a tiling system of holograms with several meters. By the technique of the heat mode lithography, the pixel pattern of the sub-wavelength was exposed on the photoresist substrate. Based on the interference fringe pattern of the 800 nm pixel pitch, using the reduction exposure technique, we fabricated a hologram of the pixel pitch of the submicron like 320 nm with 80 degree of wide viewing angle.
