A near-eye display system, virtual reality equipment and augmented reality equipment

Abstract

Provided are a near-eye display system, virtual-reality device, and augmented-reality device. A near-eye display system comprises a laser light source (261), a beam-splitting component (262), a scanning optical-fiber array (263), and a first concave reflector (264); the beam-splitting component (262) comprises a number M*N of output terminals; each output terminal is provided with an optical switch; the scanning optical-fiber array (263) comprises a number M*N of optical fibers; the M*N optical fibers are respectively connected to the M*N output terminals; M and N are positive integers greater than or equal to 2; when passing through the beam-splitting component (262), the laser light emitted by the laser light source (261) is split into M*N light beams; a light beam outputted from the output terminal corresponding to an optical switch in an activated state on the beam-splitting component (262) passes through the scanning optical-fiber array (263), and is then reflected into the human eye by the first concave reflector (264). The light beam outputted by each optical fiber is conical, therefore the width of the light beam increases continuously with an increase in the optical path; thus the exit-pupil diameter of the near-eye display system is increased and the strict limitations on the position of the eye during observation are 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...
