Hologram functional screen and fabrication method

The invention provides a hologram functional screen. When the hologram functional screen is placed on a reference plate PR, the spatial spectrum of the input information of the view information Imn carried by each spatial spectrum can be broadened with respect to spatial sampling angle Omega mn. The broadening is made such that the output spatial spectrum of each view Imn reaches each other but does not overlap to make sure the digital holographic spatial spectra of the recovered three-dimensional spatial information are restored continuously and completely. In other words, for each pixel Hjk of said hologram functional screen (1), the broadening angle of the spatially-unidirectional input light happens to be the spatial sampling angle Omega mn so as to obtain the holographic three-dimensional display aiming at restoring complex wave front. The invention also discloses a method for fabricating the hologram functional screen.
