We have previously proposed an aerial display method classified under the Pancharatnam-Berry phase optical elements, consisting of polarization diffraction gratings, wavelength plates, recursive reflective mirrors, and right-angle prisms. In this presentation, we report on the development of an aerial display method using a hybrid Fresnel lens integrating a polarization diffraction grating and a polarization diffraction Fresnel lens, aiming for further system miniaturization and simplification.
