Experimental demonstrations of different vectorial holograms. (IMAGE)
Caption
Experimental demonstrations of different vectorial holograms. Target holographic images to be reconstructed: (a) a vectorial clock; (g) a vectorial flower; (m) a vectorial flying bird. Segments and circles denote local polarization states of the images. Panels (b), (h) and (n) depict the experimentally observed patterns as three fabricated metahologram samples are illuminated by left-circular-polarized (LCP) light at 1064 nm, respectively. Panels (c)-(f), (i-l) and (o)-(r) depict the polarization filtered patterns with a rotatable polarizer placed at different angles in front of the charge-coupled device, as three metahologram samples are illuminated by LCP light at 1064 nm, respectively.
