Abstract
Embodiments include an optical system that may be included in a waveguide display. An example optical system includes a first waveguide having a first transmissive diffractive in-coupler (DG1) and a first diffractive out-coupler (DG6) and a second waveguide having a second transmissive diffractive in-coupler (DG2), a reflective diffractive in-coupler (DG3), a second diffractive out-coupler (DG4), and a third diffractive out-coupler (DG5). The second transmissive diffractive in-coupler (DG2) is arranged between the first transmissive diffractive in-coupler (DG1) and the reflective diffractive in-coupler (DG3) in an input region.
