Abstract

The present application provides a waveguide light field display device and head-mounted augmented reality glasses, wherein the waveguide light field display device includes: a waveguide lens, a plurality of coupling units, a coupling unit and a plurality of optical machines, the coupling unit The number of the waveguide lens is equal to the number of the optical machine; the shape of the waveguide lens is a curved surface, and the focus of the curved surface is located on the same side of the waveguide lens; The orthographic projection of the input unit on the waveguide lens is evenly distributed along the circumference, and the orthographic projection of the outcoupling unit on the waveguide lens is surrounded by the circle formed by the orthographic projections of multiple incoupling units on the waveguide lens; one incoupling unit corresponds to one light The parallel light beam emitted by the optical machine can enter the waveguide lens through the corresponding coupling unit. The refraction angle of the parallel beam emitted by the optical machine when entering the waveguide lens is greater than the critical angle of total reflection of the waveguide lens. After the above design, it is beneficial to reduce Dimensions of the waveguide mirror.

Description

technical field [0001] The present application relates to the technical field of image display, in particular, to a waveguide light field display device and head-mounted augmented reality glasses. Background technique [0002] The waveguide light field display device can realize augmented reality technology. The waveguide light field display device includes a waveguide lens. During the working process of the waveguide light field display device, the light propagating inside the waveguide lens can be exported to the waveguide lens, and the exported light will appear in the human eye. Imaging on the retina, so that the user can observe a three-dimensional virtual image. [0003] The waveguide lens in the existing waveguide light field display device is a flat waveguide lens, and the light from this type of waveguide lens is perpendicular to the waveguide lens, so when the viewing angle is large, the size of the waveguide lens will be reduced. Too large, which is not conducive...
