Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and through specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0029] figure 1 is a side view of a traditional reflecting telescope system. Such as figure 1 As shown, the reflective telescope system includes a curved primary mirror 10 and a curved auxiliary mirror 20, the curved auxiliary mirror 20 is aligned with the opening on the curved primary mirror 10, and the incident light 100 is reflected to the curved auxiliary mirror by the reflection surface of the curved primary mirror 10. The reflective surface of the mirror 20 is t...

Abstract

The invention discloses a reflective superstructure surface primary mirror, a reflective superstructure surface auxiliary mirror and a telescope system. The reflective superstructure surface primary mirror includes a transparent substrate and a primary mirror superstructure surface function unit pattern on the transparent substrate, wherein the primary mirror superstructure surface function unit pattern satisfies primary mirror phase distribution, the primary mirror superstructure surface functional unit pattern includes a primary mirror superstructure surface function structure located withina set annular region, the primary mirror superstructure surface function structure includes multiple primary mirror superstructure surface function units, the primary mirror superstructure surface function units include anisotropic primary mirror subwavelength structures, phases introduced by the anisotropic primary mirror subwavelength structures satisfy primary mirror phase distribution, the set annular region forms a light transmission hole, and light reflected by the reflective superstructure surface auxiliary mirror is focused through the light transmission hole. The reflective superstructure surface primary mirror is advantaged in that a planar reflective superstructure surface is realized for the design of the reflective telescope system, and problems of high difficulty in preparation, slow processing speed, high cost and large volume of a conventional reflective telescope system are solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of metasurfaces, in particular to a reflective metasurface primary mirror, auxiliary mirror and telescope system. Background technique [0002] Traditional reflective telescope systems mainly include Newtonian reflective telescope systems, Cassegrain reflective telescope systems and Gregory reflective telescope systems, all of which are composed of primary mirrors and auxiliary mirrors. Focusing and imaging can be realized after external light is reflected by the primary mirror and the auxiliary mirror in turn. The primary mirrors of the above three reflecting telescope systems are all concave mirrors, and their auxiliary mirrors are plane mirrors, convex mirrors and concave mirrors respectively. The successful implementation of these systems requires careful design of the curved mirrors in which ideal phase tuning and wavefront shaping are achieved through continuous geometric curvatu...
