Title:
EYEPIECE FOR VIRTUAL, AUGMENTED AND MIXED REALITY SYSTEMS
Document Type and Number:
Japanese Patent JP2022190067
Kind Code:
A
Abstract:
To provide a favorable eyepiece for virtual, augmented and mixed reality systems.SOLUTION: There is provided an eyepiece waveguide for an augmented reality. The eyepiece waveguide can include a transparent substrate with an input coupler region, first and second orthogonal pupil expander (OPE) regions, and an exit pupil expander (EPE) region. The input coupler region can be positioned between the first and second OPE regions and can divide and redirect an input light beam that is externally incident on the input coupler region into first and second guided light beams that propagate inside the substrate, with the first guided beam being directed toward the first OPE region and the second guided beam being directed toward the second OPE region. The first and second OPE regions can respectively divide the first and second guided beams into a plurality of replicated spaced beams. The EPE region can redirect the replicated beams from both the first and second OPE regions so that they exit from the substrate.SELECTED DRAWING: Figure 13A
