Problems solved by technology
[0003] At present, in many AR glasses solutions, people with ametropic eyes usually correct their vision by adding myopia or hyperopia lenses in front of the AR module when using AR glasses. However, the AR glasses module itself has a certain weight. At the same time, the traditional Myopia lenses and hyperopia lenses are also relatively thick, which leads to ametropia. When people use AR glasses, the overall equipment is heavy and difficult to wear.

The embodiment of the invention relates to the technical field of optics, in particular to a metasurface structure lens, a manufacturing method of the metasurface structure lens and a near-to-eye display system. According to the invention, the manufacturing method comprises the steps: the phases of a diopter lens at different positions of the lens are obtained, the diopter lens being used for correcting the vision of a user; according to the phase and a preset structure database, nano-structure units of the metasurface structure lens at different positions are determined, and the preset structure database comprises a basic phase and a nano-structure unit corresponding to the basic phase; and the metasurface structure lens is obtained according to the nano-structure units of the metasurface structure lens at different positions. According to the invention, the metasurface structure lens manufactured through the manufacturing method can be used for correcting the vision of a user, and when the metasurface structure is applied to a near-eye display system, the vision of the user can be corrected, and the overall equipment weight can be reduced.
Description
technical field [0001] The embodiments of the present invention relate to the field of optical technology, and in particular to a metasurface structured lens, a manufacturing method thereof, and a near-eye display system. Background technique [0002] Augmented reality (Augment Reality, AR) glasses combine intelligent algorithms and special optical waveguide structures, which can combine and superimpose virtual information and real information and present them to human eyes. Because AR technology has the function of augmented reality, it has a wide range of applications in military industry, medical treatment, education, and entertainment industries. [0003] At present, in many AR glasses solutions, people with ametropic eyes usually correct their vision by adding myopia or hyperopia lenses in front of the AR module when using AR glasses. However, the AR glasses module itself has a certain weight. At the same time, the traditional The short-sighted and long-sighted lenses ...
