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.

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.
