Abstract | An optical device is provided. The device includes a first Pancharatnam-Berry phase ("PBP") lens (605), and a second PBP lens (610) stacked with the first PBP lens. Each of the first PBP lens and the second PBP lens includes a liquid crystal, LC, layer (115). Each side of the LC layer is provided with a continuous electrode (215) and a plurality of patterned electrodes (225). The patterned electrodes in the first PBP lens are arranged non-parallel to the patterned electrodes in the second PBP lens.
L'invention concerne un dispositif optique. Le dispositif comprend une première lentille de Pancharatnam-Berry ("PBP") (605), et une seconde lentille PBP (610) empilée avec la première lentille PBP. Chacune de la première lentille PBP et de la seconde lentille PBP comprend une couche de cristaux liquides, LC, (115). Chaque côté de la couche LC est pourvu d'une électrode continue (215) et d'une pluralité d'électrodes à motifs (225). Les électrodes à motifs dans la première lentille PBP sont agencées de manière non parallèle aux électrodes à motifs dans la seconde lentille PBP. |
