Detailed Description
The present application is described in further detail below with reference to the attached figures.
According to an aspect of the present application, there is provided a waveguide reflective surface, wherein the waveguide reflective surface is divided to include at least one row of reflective structures, each row of reflective structures in the at least one row of reflective structures includes a plurality of hole structures and at least one communicating structure, wherein one communicating structure is provided between each adjacent two hole structures in each row of reflective structures.
The number of rows of the reflecting structures on the reflecting surface of the waveguide is not limited, and in practical application, the reflecting structures can be selected according to optical design requirements. The application is also not limited to the number of aperture structures in each row of reflective structures. It should be noted that, because one communicating structure is provided between every two adjacent hole structures in each row of the reflecting structures, the number of the communicating structures in each row of the reflecting structures is 1 less than that of the hole structures.
Wherein each communication structure is used for communicating two hole structures connected with the communication structure. In some embodiments, the structural characteristics (e.g., width, length, shape, etc.) of each communicating structure on the waveguide reflecting surface may be the same or different, for example, the waveguide reflecting surface includes two rows of reflecting structures, each communicating structure in the first row of reflecting structures has a length (which may be considered as equivalent to the interval between two hole structures) of 2mm and a width of 0.3mm, each communicating structure in the second row of reflecting structures has a length of 2.5mm and a width of 0.4mm, and the length and width of the communicating structure in each row of reflecting structures are the same in this example, but those skilled in the art will understand that the structural characteristics may be different even for different communicating structures in the same row of reflecting structures.
In some embodiments, each communicating structure includes an upper boundary and a lower boundary, the shape of the two boundaries may be any feasible shape, such as an arc shape, a linear shape, an irregular shape, and the like, and the shape of each communicating structure may be the same or different, and the application is not limited thereto. In practical applications, the structural features of the connected structures can be designed based on practical requirements. The problem of image skipping during the movement of the pupil can be greatly improved by the communicating structure between each two adjacent hole structures in each row.
In some embodiments, the spacing between each adjacent two aperture structures in each row of reflective structures is less than 3mm, and the width of the communicating structure is less than 0.5 mm.
In some embodiments, each aperture structure corresponds to a small aperture reflecting surface, and the structural characteristics of the respective aperture structures on the reflecting surface of the waveguide may be the same or different. In some implementations, the structural features include, but are not limited to, the shape of the pore structure, the size of the pore structure; alternatively, the shape of the pore structure includes, but is not limited to, circular, oval, rectangular (including square), hexagonal; optionally, the dimensions of the pore structure include the size, length, width, pore diameter (e.g., the diameter of the pore structure or the diameter of the circumscribed circle), etc. of its respective corners.
In some embodiments, the structural characteristics of each hole structure in the at least one row of reflecting structures are the same, i.e. the structural characteristics of each hole structure on the reflecting surface of the waveguide are the same. In some embodiments, the structural characteristics of the respective aperture structures in the at least one row of reflective structures are not identical, e.g. the aperture structures in the same row of reflective structures have different structural characteristics, and e.g. the aperture structures in different rows of reflective structures have different structural characteristics.
In some embodiments, for a hole structure that is circular in shape, the hole structure has a diameter of less than 1.5 mm. In some embodiments, for a pore structure that is non-circular in shape, the pore structure has a minimum circumscribed circle diameter of less than 2 mm. Because the diameter or the minimum circumcircle of the hole structure is directly smaller, the thin beams can realize clear imaging of multiple focal planes.
