Claim One:
1. A depth camera assembly (DCA) comprising: a projector configured to emit a tiled structured light (SL) pattern onto one or more objects in a local area, each illumination source of the projector comprising: a plurality of light emitters that emit a plurality of light beams, an augmented diffractive optical element (ADOE) configured to diffract at least a portion of the light beams to form a first SL pattern projection, the first SL pattern projection having a field-of-view (FOV) corresponding to a first tileable boundary, the ADOE being designed with: a pattern mask that prevents projection of light that would otherwise be diffracted into an area outside of the first tileable boundary, wherein the first SL pattern projection is combined with at least a second SL pattern projection into the tiled SL pattern illuminating the one or more objects in the local area; a detector configured to capture one or more images of the one or more objects in the local area illuminated by the tiled SL pattern; and a controller configured to determine depth information for the one or more objects in the local area using the one or more images.
