    摘要： 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 ωmn. 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. Output of full spatial spectrums of the object O is realized through a spatial spectrum limited stretching function of a holographic functional screen placed on the reference surface PR which is used on discrete spatial spectrum input image information, thereby achieving digital holographic display intended to restore complex wavefronts.

    摘要： 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. The method for manufacturing hologram projection screen according to the present invention includes the steps of: 1) recording hologram lens information on photoresist plate; 2) metalizing the photoresist plate that has been exposed, to produce the nickel master plate of hologram lens array through electroforming and recombining; 3) using the above master plate to embossing thermoplastic material, to obtain screen body, on which the information of hologram lens array are arranged. The present invention can provide a variety of display contents.
