Abstract:

An aerial display system using a hybrid-geometric phase lens (HGPL) was proposed. Based on the HGPL function, which is integrated the functions of polarization diffraction and imaging, the proposed aerial display system has the advantages of a compact and simple design, along with high efficiency in generating aerial images. The scheme’s feasibility was demonstrated experimentally using an HGPL fabricated from photoalignable liquid crystal polymer film. The proposed system can be applied as a compact/high efficiency/clear aerial display.
