HOLOGRAPHIC THREE-DIMENSIONAL DISPLAY SYSTEM AND METHOD

A holographic three-dimensional display system comprising a spatial spectrum parallel focus capturing device, a spatial spectrum holographic encoding device, and a discrete spatial spectrum restoring device. The system utilizes planar pixel information (J*K*M*N) of a flat panel display to convert discrete spatial spectrum image information (Imn) via holographic encoding into a discrete spatial spectrum holographically encoded image (Sjk), utilizes a corresponding lens array to restore a discrete spatial spectrum of the image, and then implements discrete spatial spectrum broadening at a sampling angle of ωmn via a holographic function screen, thus implementing complete spatial spectrum restoration of an original three-dimensional space, and producing true three-dimensional display visible to the human eye. Also provided is a holographic three-dimensional display method.
