Abstract
A system includes one or more waveguides, and a plurality of grating sets coupled with the one or more waveguides. A plurality of combinations of gratings from the grating sets are configurable to direct an image light to propagate through a plurality of sub-eyeboxes forming an uncompressed eyebox. The system also includes a controller configured to selectively configure one or more combinations of gratings to operate in a diffraction state to direct the image light to propagate through one or more sub-eyeboxes forming a compressed eyebox having a size smaller than a size of the uncompressed eyebox.
