| description | Systems and methods for providing holographic waveguide display using integrated gratings in accordance with various embodiments of the invention are illustrated. One embodiment includes a waveguide display including a source of light, and a first waveguide including a grating structure including first and second gratings, and an input coupler configured to couple a first field-of-view portion of light, and couple a second field-of-view portion of light, wherein the first grating is configured to provide beam expansion in a first direction for the first field-of-view portion of light, and provide beam expansion in the first direction and beam extraction towards a viewer for the second field-of-view portion of light, the second grating is configured to provide beam expansion in a second direction for the second field-of-view portion of light, and provide beam expansion in the second direction and beam extraction towards a viewer for the first field-of-view portion of light. |
