A reflective surface of the first reflector or the second reflector includes a plurality of sub-wavelength structures with different functions and arranged according to preset positions. The beam splitter is configured to: transmit a first portion of incident light and reflect a second portion of the incident light, transmit a portion of light reflected by the first reflector, and reflect a portion of light reflected by the second reflector. The first reflector is arranged at an angle of 45°, −45°, 135°, or −135° with respect to the beam splitter, and is configured to reflect the second portion of the incident light. The second reflector is arranged perpendicular to the first reflector, and is configured to reflect the first portion of the incident light.

Abstract: A symmetrical metasurface optical device includes a substrate and a plurality of nanopillars symmetrically arranged at a surface of the substrate. The plurality of nanopillars have different optical properties. When a center of symmetry of the plurality of nanopillars coincides with a center of the substrate, nanopillars of a same optical property among the plurality of nanopillars are distributed non-uniformly and symmetrically. Or when the nanopillars of the same optical property among the plurality of nanopillars are distributed uniformly and symmetrically, the center of symmetry of the plurality of nanopillars does not coincide with the center of the substrate.
