Title:
AUGMENTED REALITY HOLOGRAPHIC DISPLAY USING OPTICAL WAVEGUIDE AND HOLOGRAPHIC OPTICAL ELEMENT
Document Type and Number:
WIPO Patent Application WO/2021/112301
Kind Code:
A1
Abstract:
Provided is a technology for implementing an AR optical waveguide display capable of showing a hologram image by means of a small and simple system configuration by using an HOE. A holographic display according to an embodiment of the present invention comprises: a light source module for emitting a beam; an optical waveguide through which the emitted beam is incident and propagated; a plurality of holographic optical elements (HOEs) for propagating the beam incident to the optical waveguide inside the optical waveguide while totally reflecting the beam; and a modulator for expressing a holographic image through the progressing beam and propagating the beam to the inside of the optical waveguide while totally reflecting the beam. Accordingly, it is possible to implement, as a small and simple system, an optical waveguide display showing an AR hologram by using an optical waveguide and an HOE.
