The present invention provides an optical waveguide structure, an AR (Augmented Reality) device optical imaging system and an AR (Augmented Reality) device. The optical waveguide structure includes afirst light guide plate and a second light guide plate which are attached to each other, wherein the first light guide plate is provided with a first main surface and a second main surface disposed oppositely; the first main surface or the second main surface is provided with a reflection microstructure; and the second light guide plate is attached to the reflection microstructure; and the reflection microstructure is composed of a plurality of individual concave and convex teeth arranged sequentially. With the optical waveguide structure of the invention adopted, large-field of view angle, ultra-thin-thickness and high-resolution imaging effects are realized, and user experience can be greatly improved. The optical waveguide structure has the advantages of simple manufacture and assembly,high mass production yield and low cost.
Description
technical field [0001] The present invention relates to the technical field of AR device optical imaging, and in particular to an optical waveguide structure, an AR device optical imaging system and an AR device. Background technique [0002] At present, AR (Augment Reality) technology has attracted more and more attention and research. AR is augmented reality technology, which is to superimpose virtual information on real world information, and then transmit it to itself in a way that humans can accept, including Sight, hearing, taste, touch and other senses assist human senses to receive information that cannot be easily obtained from the real world, and at the same time achieve real-time interaction. [0003] For AR optical display technology, it has gone through the stages of off-axis optics, prisms, curved prisms, and waveguide optics. Among them, the geometric light waveguide technology solves the problem of lateral transmission of light, and has the advantages of larg...
