An apparatus comprising: at least one waveguide having an in-coupler; a first display configured to generate a first image and a second display configured to generate a second image; and a lens system configured to direct the first image and the second image onto the in-coupler; wherein the in-coupler is configured to use different diffractive orders to couple the first image into the waveguide and to couple the second image into the waveguide. Claim: 2. (canceled) Claim: 3. The apparatus of claim 1, wherein the lens system has an optical axis, and the first display and the second display are arranged on opposite sides of the optical axis. Claim: 4. The apparatus of claim 1, wherein the in-coupler is configured to couple the first image into the waveguide using a positive diffractive order and to couple the second image into the waveguide using a negative diffractive order. Claim: 5. The apparatus of claim 1, wherein the in-coupler is configured to couple at least one of the first image and the second image into the waveguide using a diffractive order having an absolute value higher than one. Claim: 6. The apparatus of claim 1, wherein the lens system has an optical axis, and the optical axis does not intersect any display of the apparatus. Claim: 7. The apparatus of claim 1, wherein the waveguide further comprises an out-coupler and at least one eye pupil expander along at least a first optical path from the in-coupler to the out-coupler. Claim: 8. The apparatus of claim 1, wherein the waveguide further comprises an out-coupler and a first and a second eye pupil expander along a first optical path from the in-coupler to the out-coupler, the first and second eye pupil expanders being configured to guide the first image to the out-coupler. Claim: 9. The apparatus of claim 8, wherein the waveguide further comprises a third and a fourth eye pupil expander along a second optical path from the in-coupler to the out-coupler, the third and fourth eye pupil expanders being configured to guide the second image to the out-coupler. Claim: 10. The apparatus of claim 8, wherein a grating pitch Λe of at least one of the eye pupil expanders is determined as follows: [mathematical expression included] where ϕK is half of the deviation angle, [mathematical expression included] where n2 is the refractive index of the material of the waveguide, θdg is a maximum grazing incident angle inside the waveguide, M is the diffraction order, λ is the wavelength of the light coupled into the waveguide, and Δϕ is the maximum angle of the deviated light given by: [mathematical expression included] [mathematical expression included] [mathematical expression included] [mathematical expression included] [mathematical expression included] Claim: 11. A method comprising: generating a first image on a first display and a second image on a second display; and using a lens system, directing the first image and the second image onto an in-coupler of a waveguide; wherein the in-coupler is configured to use different diffractive orders to couple the first image into the waveguide and to couple the second image into the waveguide. Claim: 12. (canceled) Claim: 13. The method of claim 11, wherein the lens system has an optical axis, and the first display and the second display are arranged on opposite sides of the optical axis. Claim: 14. The method of claim 11, further comprising, using the in-coupler, coupling the first image into the waveguide using a positive diffractive order and coupling the second image into the waveguide using a negative diffractive order. Claim: 15. The method of claim 11, wherein the in-coupler is configured to couple at least one of the first image and the second image into the waveguide using a diffractive order having an absolute value higher than one. Claim: 16. The method of claim 11, wherein the lens system has an optical axis, and the optical axis does not intersect any display of the apparatus. Claim: 17. The method of claim 11, wherein the waveguide further comprises an out-coupler, at least a first eye pupil expander configured to guide the first image to the out-coupler, and at least a second eye pupil expander configured to guide the second image to the out-coupler. Claim: 18. The apparatus of claim 1, wherein the first and second displays are separated by a central space without a display. Current International Class: 02; 21; 02
