Computational Holographic Imaging based on Volume Holographic Optical Element for Color Dispersion Free Holographic Virtual Display

In this paper, a multiple VHOE based computational transmission-type full-color holographic imaging is newly proposed, and with the computational holographic imaging model it is testified that a new various type of augmented-reality holographic display system could be implemented. For this, a two-stage bragg diffractions are applied through combination of two designed VHOEs for the effective removal of color dispersion.
