Embodiment Construction
[0027] 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 some, not all, embodiments of the present invention. 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.
[0028] Before introducing the technical solution in the embodiment of the present invention, first introduce the technical principle of laser scanning imaging, please refer to figure 1 , figure 1 Schematic for laser-scanned retinal imaging, such as figure 1 As shown, 101 is a laser generator, 102 is a two-dimensional scanning device, and 103 is a retina of a human eye.
[0029] For the convenience of introduction, take the imaging image with a resolution of 5*5 a...

The invention discloses a near-eye display system, a virtual reality device and an augmented reality device. The near-eye display system comprises a first image source, a second image source, a firstvertical expansion waveguide, a second vertical expansion waveguide and a horizontal expansion waveguide. Image light given out by the first image source passes the first vertical expansion waveguide,is subjected to beam expansion in the vertical direction, then passes the horizontal expansion waveguide, is subjected beam expansion in the horizontal direction, and finally, enter human eyes. Imagelight given out by the second image source passes the second vertical expansion waveguide, is subjected to beam expansion in the vertical direction, then passes the horizontal expansion waveguide, issubjected beam expansion in the horizontal direction, and finally, enter human eyes. Due to the first vertical expansion waveguide, the second vertical expansion waveguide and the horizontal expansion waveguide, the exit pupil diameter of the near-eye display system is expanded, so light output by the near-eye display system can enter pupils of eyes in a quite large range, and applicable people of the virtual reality device or the augmented reality device is increased.
Description
technical field [0001] The invention relates to the fields of virtual reality and augmented reality, in particular to a near-eye display system, a virtual reality device and an augmented reality device. Background technique [0002] Virtual reality (English: Virtual Reality; abbreviation: VR) is a computer simulation system that can create and experience a virtual world. It uses a computer to generate a simulated environment. Users are immersed in the environment, bringing users a sensory experience beyond the real life environment. In terms of vision, virtual reality technology uses computer equipment to generate images of virtual scenes, and transmits image light to human eyes through optical devices, so that users can fully experience the virtual scene visually. [0003] Augmented reality (English: Augmented Reality; abbreviation: AR) is a technology that uses virtual objects or information to enhance the reality of real scenes. Augmented reality technology is usually b...
