Problems solved by technology

Since the images presented by the existing virtual reality technology or augmented reality technology converge on a virtual plane, the human eye needs to be in a state for a long time before it can capture the image, which violates the natural characteristics of the human eye and is called "false reality". 3D" display technology, long-term use will cause users headaches, dizziness, and even damage to vision
[0004] Therefore, it is necessary to use "true 3D" display technology to realize virtual reality. However, the existing "true 3D" reality technology is hindered due to its shortcomings. Image capture requirements within the range

Embodiment Construction

[0039] It can be seen from the background art that the virtual retinal projection system in the prior art cannot increase the exit pupil size of the virtual retinal projection system.

[0040] In order to solve the problem, the present invention provides a virtual retinal projection system, comprising:

[0041] a projection module adapted to generate a thin beam of light for the image to be displayed;

[0042] A discrete beam splitter, adapted to receive the thin beam and split the thin beam to generate beams in different discrete directions;

[0043] The reflective device is adapted to receive the light beams in different discrete directions and reflect them to obtain reflected light beams. The reflected light beams form various viewpoints, and each of the viewpoints can form the image to be displayed that meets the complete requirements of human visual viewing. virtual image, and the distance between each adjacent viewpoint is smaller than the diameter of the pupil of the h...

Abstract

The present invention provides a virtual retinal projection system, comprising: a projection module, suitable for generating thin beams of images to be displayed; light beams in different directions; reflective devices are adapted to receive the light beams in different discrete directions and reflect them to obtain reflected light beams. The reflected light beams form various viewpoints. A virtual image of the image to be displayed, and the distance between each adjacent viewpoint is smaller than the diameter of the pupil of the human eye. The virtual retinal projection system provided by the embodiment of the present invention can increase the exit pupil of the virtual retinal projection system.

Description

technical field [0001] The invention relates to the field of virtual reality, in particular to a virtual retinal projection system. Background technique [0002] At this stage, virtual reality technology or augmented reality technology has been developed rapidly. However, after long-term use of related equipment, it will cause visual impairment, damage to the eye convergence function, and the consequences of being unable to focus normally. [0003] 3D display enables users to feel a sense of three-dimensionality by providing parallax images with subtle differences to the left and right eyes of the user respectively. Since the images presented by the existing virtual reality technology or augmented reality technology converge on a virtual plane, the human eye needs to be in a state for a long time before it can capture the image, which violates the natural characteristics of the human eye and is called "false reality". 3D" display technology, long-term use will cause users h...
