Eyepiece for near-to-eye type optical system

Abstract

The invention discloses an eyepiece for a near-to-eye type optical system. The eyepiece comprises an illumination module, a reflection module, a viewing area and light guide columns, wherein the illumination module is used for providing image CGI (computer generated imagery) light produced by a computer in the forward propagation path in the eyepiece; the reflection module is arranged at the end, opposite to the illumination module, of the eyepiece, and the CGI light marching along with the forward propagation path in the eyepiece is guided out again after the propagation path is changed with 90 degrees; the viewing area is aligned with an eye of a user; the illumination module is communicated with the reflection module through a first light guide column, and is communicated with the viewing area through a second light guide column; the first light guide column is vertically arranged to the second light guide column. The eyepiece has the advantages that the problem of blocking of view field is solved by adjusting the eyepiece structure; by additionally arranging a primary end surface transmitter, the secondary magnification is realized, so as to solve the problem of increasing of distortion degree of the image due to overlarge times of primary magnification.

Description

Technical field [0001] The present invention relates to the technical field of the optical field, in particular to an eyepiece for a near-eye optical system. Background technique [0002] Chinese patent ZL201280038118.2 invented an eyepiece for the near-eye optical system of a head-mounted display, that is, GOOGLE glasses. From the feedback of practical applications, due to the structural design characteristics of the eyepiece, the user’s visual field on both sides of the eye will be It is blocked by the eyepiece, and because of the use of a primary end emitter, the magnification effect is limited. If the magnification is increased by adjusting the curvature of the end emitter, the image distortion will increase. Summary of the invention [0003] The purpose of the present invention is to provide an eyepiece for a near-eye optical system, which solves one or more of the above-mentioned prior art problems. [0004] The present invention provides an eyepiece for a near-eye optical sy...

[0002] Chinese patent ZL201280038118.2 invented an eyepiece for the near-eye optical system of a head-mounted display, that is, GOOGLE glasses. According to the actual application feedback, due to the structural design characteristics of the eyepiece, the user's vision on both sides of the human eye will be different when using it. Obstructed by the eyepiece, and due to the use of a primary end-face emitter, the magnification effect is limited. If the magnification is increased by adjusting the curvature of the end-face emitter, the image distortion will increase.
