  • Publication number: 20160291545
    Abstract: A holographic three-dimensional display system and a holographic three-dimensional display method are disclosed. Plane pixel information (J*K*M*N) of the flat panel display is reasonably used to convert the discrete spatial spectrum image information Imn into the discrete spatial spectrum image Sjk by using holographic coding conversion, the discrete spatial spectrum thereof is restored by using corresponding lens arrays, and the discrete spectrum widening of the sampling angle ?mn is realized by the holographic function screen so as to realize complete spatial spectrum restoring of an original three-dimensional space. By using the lens arrays and the holographic function screen, an inherent conflict between the imaging quality of a microlens array and the resolution of a displayed three-dimensional image in integration photography is effectively overcome, and eye visible perfect true three-dimensional display is realized, thereby obtaining eye visible prefect true three-dimensional display.

  • Patent number: 8890932
    Abstract: A real-time color holographic three-dimensional (3D) display system and method realized by using principles of digital holographic display and a common photographing/projection device array system are provided. For an object O to be displayed, an array of M×N cameras which are anchored to a certain reference point R in a space corresponding to the object O is used to perform spatial spectrum sampling and capturing on any spatial spectrum surface S of the object O with a sampling density being a spatial sampling angle ?mn. Each acquired spatial spectrum view image Imn is projected by a corresponding array of M×N projectors in each spatial spectrum capturing direction to a reference surface PR necessary for restoring 3D information of the original object O.

  • Patent number: 7880945
    Abstract: A method for manufacturing a hologram projection screen includes the steps of: 1) recording hologram lens information on a photoresist plate; 2) metalizing the photoresist plate that has been exposed, to produce a master nickel plate of a hologram lens array through electroforming and joining; and 3) using the master nickel plate to emboss thermoplastic material, to obtain a screen body, on which the information of the hologram lens array is arranged. The hologram projection screen manufactured by this method can provide a variety of display contents.

  • Publication number: 20070146842
    Abstract: The present invention provides a hologram projection screen and its manufacturing method and system as well as its applications. The present hologram projection screen includes a screen body, wherein an array of hologram lenses are arranged onto said screen body, the hologram lenses are arranged equably onto the screen body vertically and horizontally, adjacently to each other. The hologram lenses have a circular or elliptical shape in said screen body, or have a regular polygonal shape in said screen body. The hologram lens may be a set of lenses.
