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.

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.

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.
