Embodiment Construction
[0029] 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.
[0030] 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.
[0031] 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 is characterized in that the near-eye display system comprisesN scanning light sources which are parallelly arranged in the vertical direction and a horizontal expansion waveguide, wherein N is a positive integer larger than or equal to 2. Scanning light given out by the N scanning light sources is subjected to beam expansion through the horizontal expansion waveguide and then enters human eyes. According to the invention, by use of the technical scheme thatthe scanning light given out by the N scanning light sources which are parallelly arranged in the vertical direction is subjected to beam expansion, it seems that the exit pupil diameter of the near-eye display system is expanded through the horizontal expansion waveguide, so light output by the near-eye display system can enter pupils of eyes in a quite large range, strict limitations on positions of eye observation are reduced or avoided 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...
