Abstract
A display system may include a waveguide plate comprising opposing parallel surfaces, an in-coupling grating, an expansion grating, and an out-coupling grating. The display system may include a projection system configured to direct input light toward the in-coupling grating and a translation assembly configured to translate the waveguide plate relative to the projection system along an axis. The in-coupling grating may be configured to diffract the input light to cause total internal reflection of the input light within the waveguide plate. The expansion grating may be configured to (i) cause replica expansion of the input light and (ii) cause the input light to propagate within the waveguide plate toward the out-coupling grating. The out-coupling grating may be configured to (i) cause replica expansion of the input light replica expanded by the expansion grating and (ii) diffract the input light replica expanded by the expansion grating outward from the waveguide plate.
