Abstract: Provided are a linearly polarized light conversion element, a manufacturing method and a linearly polarized light conversion system. The linearly polarized light conversion element includes a substrate (1); a metasurface (2) located on the substrate (1); where the metasurface (2) includes at least one light field regulation control region (100), each light field regulation control region (100) includes at least one metasurface functional unit (20), the metasurface functional unit (20) includes an anisotropic sub-wavelength structure (201), and a long-axis direction of each sub-wavelength structure (201) in a same light field regulation control region (100) is the same.

Abstract: Provided are a reflective metasurface primary mirror and secondary mirror, and a telescope system. The reflective metasurface primary mirror includes a transparent substrate and a primary mirror metasurface functional unit pattern disposed on the transparent substrate. The primary mirror metasurface functional unit pattern includes an anisotropic primary mirror subwavelength structure disposed in a set annular region, and a phase introduced by the primary mirror subwavelength structure satisfies a primary mirror phase distribution. The set annular region encircles a light-transmissive hole, and light reflected by the reflective metasurface secondary mirror is focused through the light-transmissive hole.
