Abstract

The invention relates to a holographic optical waveguide device for three-dimensional dynamic display and augmented reality display equipment. The holographic optical waveguide device comprises an optical-mechanical system which comprises a laser illumination system and a micro-display, wherein the micro-display is used for loading a three-dimensional computed hologram obtained after the wavefrontcoding of a three-dimensional scene, light waves irradiated to the micro-display are modulated by the laser illumination system according to the three-dimensional computed hologram, and the modulatedlight waves carrying three-dimensional scene wavefront information distribution enter a lens system; the lens system which is used for filtering the light wave carrying the three-dimensional scene wavefront information distribution and then emitting the light wave into a multiplexing volume holographic grating; the multiplexing volume holographic grating which is used for coupling the light wavecarrying the three-dimensional scene wavefront information distribution into a waveguide plate; the waveguide plate which transmits the light wave carrying the three-dimensional scene wavefront information distribution to a coupled-out multiplexing body holographic grating in a total reflection mode; and the coupled-out multiplexing volume holographic grating which is used for coupling the light wave carrying the three-dimensional scene wavefront information distribution out to human eyes.

Description

[0001] The present invention claims the priority of the Chinese patent application CN202010418635.9, and the content described in the specification, drawings and claims of the priority document is incorporated into the specification of the present invention in its entirety and is regarded as a part of the original description of the specification of the present invention. The applicant further declares that the applicant has the right to amend the description and claims of the present invention based on the priority document. technical field [0002] The present disclosure relates to the technical field of augmented reality, in particular to a holographic optical waveguide device for three-dimensional dynamic display and an augmented reality display device. Background technique [0003] Near-eye display means that while the observer is viewing real objects outside, information such as images or data superimposed in the real environment can also be viewed. It provides the func...
