Near-to-eye display system, virtual reality equipment and augmented reality equipment

Abstract

The invention discloses a near-to-eye display system, virtual reality equipment and augmented reality equipment. The near-to-eye display system comprises a laser light source, a light splitting assembly, a scanning optical fiber array and a first concave surface reflector, wherein the light splitting assembly comprises M*N output ends; each output end is provided with an optical switch; the scanning optical fiber array comprises M*N optical fiber bundles; the M*N optical fiber bundles and the M*N output ends are connected one by one; the M and the N are positive integers greater than or equal to 2; laser emitted from the laser light source is split into M*N light beams when passing through the light splitting assembly; light beams output by the output ends corresponding to the optical switches, in an open state, in the light splitting assembly are reflected into the human eye by the first concave surface reflector after passing through the scanning optical fiber array. The light beams output by each optical fiber bundle are in a conical shape, and the width of each light beam can be continuously increased along with the light path increase, so that the exit pupil diameter of the near-to-eye display system can be increased; the strict restriction on the human eye observation position is reduced or avoided.

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...
