Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0047] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relationship between the components in a certain posture (as shown in the accompanying drawings). Relative positional relationship, movement conditions, etc., if the specific posture changes, the directional indication will also change accordingly.
[0048]In addition, in th...

Abstract
The invention discloses an optical waveguide component, a display system, an augmented reality device and a display method. The optical waveguide component is applied to an augmented reality device. The optical waveguide component includes an optical waveguide body and a first holographic element. The first holographic The element is arranged on the side of the outcoupling area of the optical waveguide body, the first holographic element is an off-axis holographic element and has optical power; light enters the optical waveguide body from the incoupling area of the optical waveguide body, And enter the first holographic element after being emitted from the outcoupling area of the optical waveguide body, and the light is emitted from the first holographic element and transmitted to the human eye. The present invention provides an optical waveguide assembly, a display system, an augmented reality device and a display method, aiming to solve the problems in the prior art that the user cannot effectively resolve the convergence adjustment conflict when using the augmented reality device, which easily causes visual fatigue, dizziness and nausea to the user question.
Description
technical field [0001] The invention relates to the technical field of optical imaging, in particular to an optical waveguide component, a display system, an augmented reality device and a display method. Background technique [0002] In augmented reality (Augmented Reality, AR) technology, a grating is usually used as an imaging element. Since the grating cannot provide optical power, the display effect of the augmented reality device will be limited. [0003] In the existing augmented reality technology using optical waveguides, in order to realize the 3D display of images, it is usually realized by means of binocular vision difference. Different images are displayed by the two eyes so that the user can produce a stereoscopic visual effect. When focusing on the virtual image plane and seeing the image clearly, the two different images passing through the retina will enable the user to observe the image with a sense of distance, but the distance sense of the image will trig...
