Title:
拡張現実ディスプレイシステムのための接眼レンズ
Document Type and Number:
Japanese Patent JP7372305
Kind Code:
B2
Abstract:
An eyepiece waveguide for an augmented reality display system may include an optically transmissive substrate, an input coupling grating (ICG) region, a multi-directional pupil expander (MPE) region, and an exit pupil expander (EPE) region. The ICG region may receive an input beam of light and couple the input beam into the substrate as a guided beam. The MPE region may include a plurality of diffractive features which exhibit periodicity along at least a first axis of periodicity and a second axis of periodicity. The MPE region may be positioned to receive the guided beam from the ICG region and to diffract it in a plurality of directions to create a plurality of diffracted beams. The EPE region may be positioned to receive one or more of the diffracted beams from the MPE region and to out couple them from the optically transmissive substrate as output beams.
