Augmented reality optical waveguide device

Abstract

The invention discloses an augmented reality optical waveguide device. The optical waveguide device comprises: a first reflecting surface, a plurality of second reflecting surfaces, and a substrate; the first reflecting surface is embedded in one end of the substrate, and an included angle between the first reflecting surface and a lower surface of the substrate is alpha; the first reflecting surface is used for coupling incident beams perpendicular to the substrate into the substrate; the plurality of second reflecting surfaces are embedded in the other end of the substrate parallel to each other at a first set distance along the longitudinal direction of the substrate; the plurality of second reflecting surfaces spaced apart from each other by a second set distance in a lateral directionof the substrate; the included angle between the second reflecting surface and the lower surface of the substrate is pi-alpha; and the plurality of second reflecting surfaces are used for respectively coupling the beams in the substrate out from the substrate in multiple front and back layers and outputting the beams into human eyes. The augmented reality optical waveguide device disclosed by theinvention increases the viewing angle of a viewer and ensures the compactness of the structure.

Description

technical field [0001] The invention relates to the field of optical devices, in particular to a reality-augmented optical waveguide device. Background technique [0002] Augmented reality (Augmented Reality, referred to as AR), augmented reality technology is a new technology that "seamlessly" integrates real world information and virtual world information. Entity information (visual information, sound, taste, touch, etc.), through computer and other science and technology, simulates and then superimposes, applies virtual information to the real world, and is perceived by human senses, so as to achieve a sensory experience beyond reality. Augmented reality technology not only shows the information of the real world, but also displays the virtual information at the same time, and the two kinds of information complement and superimpose each other. In visual augmented reality, users can see the real world including virtual information by superimposing the real world with comp...

Problems solved by technology

[0003] However, the traditional AR display technology has the fatal shortcomings of small viewing angle and insufficient compactness, especially as the expected viewing angle of the system increases, the optical module of the traditional AR display will become larger and more cumbersome, and this defect even if Reducing the quality requirements of the image can not be solved
