Abstract: Provided are a metasurface primary mirror, a metasurface secondary mirror, a method for manufacturing a metasurface primary mirror, a method for manufacturing a metasurface secondary mirror, and an optical system. The metasurface primary mirror, manufactured by using the method for manufacturing a metasurface primary mirror, includes a transparent substrate which includes a primary mirror metasurface pattern on the transparent substrate. The primary mirror metasurface is configured to satisfy a primary mirror phase distribution such that incident light reflected by a metasurface secondary mirror onto the metasurface primary mirror is reflected and focused.

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.
