The invention discloses a
berry phase metasurface-based multi-plane holographic
multiplexing method, and belongs to the field of micronano optical and holographic
multiplexing application. The
berry phase metasurface-based multi-plane holographic
multiplexing method comprises the steps of achieving phase
recovery by a 3D-Fienup
algorithm, taking different numerical values of
reproduction positions of different images, and acquiring a
computer generation holographic diagram containing all information; selecting a
metal coupling polaron as a
berry phase metasurface structure unit, achieving
phase modulation based on a berry
phase modulation principle, and enabling a polarization state to become a multiplexing path by coding a holographic phase profile conjugated with an original phase to achieve a holographic multiplexing passage selected by
circular polarization; making a metasurface phase sheet for recording the
computer generation holographic diagram, selecting an emergent
circular polarization light orthogonal to
chirality of the polarization stat, and optically reproducing a three-dimensional object or a wave surface which is recorded. The holographic multiplexing method with sub-
wavelength pixel of visible light and near-
infrared bands, ultrathinness, large
visual angle and
large capacity is provided by the invention; and moreover, the
crosstalk can be effectively reduced, and the holographic multiplexing of
circular polarization selectivity is achieved.
