Problems solved by technology

[0007] Compared with the flat structure, the curved surface structure of the convex lens has many inconveniences in preparation and use.
However, from the perspective of traditional lens production, there is no effective design method to design a lens with both a fully planar structure and the optical properties of a conventional convex lens.

Embodiment

[0056] A method for designing a metamaterial-based full-planar convex lens is used to convert an original convex lens into a full-planar convex lens. The convex surface of the original convex lens is a sphere, an ellipsoid, a paraboloid of revolution or a hyperboloid of revolution. The design methodology includes the following steps:

[0057] S01, determine the space transformation on the basis of the structure of the original convex lens;

[0058] Such as figure 1 As shown, the space CKDHLG occupied by the original convex lens is expressed as s 1 (x,y,z), the free space ABDKC on the right side of the original convex lens is expressed as s 2r (x,y,z), the free space IJHLG on the left side of the original convex lens is expressed as s 2l (x,y,z). Compress the left and right convex surfaces of the original convex lens into planes respectively, then the space s of the original convex lens 1 (x,y,z) is compressed into CDHG, denoted as s 1 '(x,y,z); free space s on the right ...

Abstract

The invention relates to a method for designing a full-planar convex lens based on meta-materials, comprising the steps as follows: S01, determining space transformation on the basis of the structure of an original convex lens; S02, selecting a function which can realize space transformation of the convex lens, and determining a complete coordinate transformation relation; and S03, calculating the material parameters of meta-materials in all the spaces of a planar convex lens based on the optical principle of transformation. Compared with the prior art, the invention designs a convex lens which has both a full-planar structure and the optical properties of a conventional convex lens, the designed convex lens has a wide range of application, the design method is simple and feasible and is easy to implement, and the designed convex lens is easy to install, debug and integrate.

Description

technical field [0001] The invention relates to a design method of a full-planar structured convex lens, in particular to a design method of a full-planar structured convex lens based on metamaterials. Background technique [0002] Lenses are basic electromagnetic and optical devices, and convex lenses are one of the important types. Due to the converging and imaging characteristics of the convex lens, it is widely used in various imaging devices and systems. [0003] The convergence and imaging of a convex lens are mainly formed by the refraction of light on the lens surface. From geometric optics, they appear as: [0004] Light rays parallel to the optical axis converge at the focal point F of the convex lens after passing through the convex lens. [0005] When the distance between the object and the lens is greater than 2 times the focal length, a reduced inverted real image will be formed on the other side of the lens; when it is greater than 1 times the focal length,...
