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.

Optical system and method for providing compressed eyebox

A method includes determining eye tracking information of an eye pupil. A method also includes selectively configuring, based on the eye tracking information, one or more combinations of gratings included in a plurality of grating sets coupled with one or more waveguides to operate in a diffraction state to direct an image light to propagate through one or more sub-eyeboxes of a plurality of sub-eyeboxes. The plurality of sub-eyeboxes define an uncompressed eyebox. The one or more sub-eyeboxes of the plurality of sub-eyeboxes define a compressed eyebox having a size smaller than a size of the uncompressed eyebox.
