  • INCOHERENT HOLOGRAPHIC IMAGING WITH METASURFACES
    Publication number: 20190113885
    Abstract: A birefringent metasurface lens formed by an array of nanoposts generates different phase profiles for different incident electromagnetic waves of different polarization. A first polarization is focused at a first focal length, while a second polarization is focused at a second focal length. A variable phase retarder and a polarizer generate interference patterns for each phase difference between the two incident polarizations. The interference patterns are used to generate a hologram, allowing reconstruction of the image of an object.
