A multiplexed holographic display video has been achieved by using a passive azo-dye-doped liquid crystal （LC） cell. Holograms formed in this cell can be refreshed in the order of several milliseconds. By angular multiplexing technique, dynamically multiplexed holographic videos are realized. Moreover, the reconstructed RGB images are merged into a color image, which illustrates the possibility of a color holographic three-dimensional （3D） display by holographic multiplexing of the LC cell.
We propose a holographic head-up AR display with adaptive brightness of ambient light based on geometry phase (GP) holographic lens and a cholesteric liquid crystal (CLC) film. By tuning the diffraction efficiency of ...
