From: Ptychography retrieval of fully polarized holograms from geometric-phase metasurfaces
a Schematic of the polarization-reconstructed and multi-directional meta-hologram. b SEM image of the fabricated meta-hologram with uniformly distributed subpixels. c Photograph of the holographic image with a series of ghost images. d SEM image of the fabricated meta-hologram with randomly distributed subpixels. e Photograph of the holographic image with pure desired images. f Close-ups of Jones matrices maps of uniformly distributed and g randomly distributed meta-hologram, with phase encoded as hue and modulus encoded as brightness. Scale bars are 2.2 µm. h Intensity values (arbitrary units), together with the corresponding SoP, of the reconstructed vectorial far field of the metasurface.
