The modulation function of holographic functional screen (HFS) in the real-time, large-size full-color (RLF), three-dimensional (3D) display system is derived from angular spectrum analysis. The directional laser speckle (DLS) method to realize the HFS is proposed. A HFS by the DLS method was fabricated and used in the experiment. Experimental results show that the HFS is valid in the RLF 3D display, and that the derived modulation function is valuable for the design of the HFS. The research results are important to realize the RLF 3D display system which will find many applications such as holographic video.

    ABSTRACT: The three-dimensional (3D) display based on the holographic functional screen is theoretically and experimentally presented. By properly designing the subholograms on the holographic functional screen, the whole 3D light field distribution can be recovered with the recorded angular spectra through the pinhole CCD camera array. The holographic functional screen is fabricated by the laser speckle method. Experimental results show that the fully continuous, natural D display is achieved without the limitations of conventional holography. Further improvements could lead to applications in industry, medical operation, military affairs, architecture design, mapping, and entertainment.

    ABSTRACT: The crosstalk severely affects the viewing experience for the auto-stereoscopic 3D displays based on frontal projection lenticular sheet. To suppress unclear stereo vision and ghosts are observed in marginal viewing zones(MVZs), aberration of the lenticular sheet combining with the frontal projector is analyzed and designed. Theoretical and experimental results show that increasing radius of curvature (ROC) or decreasing aperture of the lenticular sheet can suppress the aberration and reduce the crosstalk. A projector array with 20 micro-projectors is used to frontally project 20 parallax images one lenticular sheet with the ROC of 10 mm and the size of 1.9 m × 1.2 m. The 3D image with the high quality is experimentally demonstrated in both the mid-viewing zone and MVZs in the optimal viewing plane. The 3D clear depth of 1.2m can be perceived. To provide an excellent 3D image and enlarge the field of view at the same time, a novel structure of lenticular sheet is presented to reduce aberration, and the crosstalk is well suppressed.

    ABSTRACT: A novel method for perfect holographic display by means of lens array and holographic functional screen is proposed. The process of acquisition, coding, restoration and display is described in detail. It provides an efficient way to transfer the 2D redundant information for human vision to the perfect 3D display for human eyes. A holo-video system based on commercial 4K displayer is demonstrated as the result.
