摘要	A virtual image generation system comprises a planar optical waveguide having opposing first and second faces, an in-coupling (IC) element configured for optically coupling a collimated light beam from an image projection assembly into the planar optical waveguide as an in-coupled light beam, a first orthogonal pupil expansion (OPE) element associated with the first face of the planar optical waveguide for splitting the in-coupled light beam into a first set of orthogonal light beamlets, a second orthogonal pupil expansion (OPE) element associated with the second face of the planar optical waveguide for splitting the in-coupled light beam into a second set of orthogonal light beamlets, and an exit pupil expansion (EPE) element associated with the planar optical waveguide for splitting the first and second sets of orthogonal light beamlets into an array of out-coupled light beamlets that exit the planar optical waveguide.

主权项	1 . A virtual image generation system comprising: a planar optical waveguide comprising a plurality of substrates including a primary substrate having a first thickness and at least a secondary substrate respectively having at least one second thickness, and at least one semi-reflective interface disposed between the substrates, the first thickness being at least twice each of the at least one second thickness; an in-coupling (IC) element configured for optically coupling a collimated light beam from an image projection assembly for propagation as an in-coupled light beam within the planar optical waveguide, wherein the at least one semi-reflective interface is configured for splitting the in-coupled light beam into a plurality of primary light beamlets that propagate within the primary substrate; and one or more diffractive optical elements (DOEs) associated with the planar optical waveguide for further splitting the plurality of primary light beamlets into an array of out-coupled light beamlets that exit a face of the planar optical waveguide.
