Claim 18:
19. A method comprising:
projecting a pattern of light on an object using a projector, the projector including:
an array of vertical cavity surface emitting lasers (VCSELs) to emit the light;
an array of micro-lenses coupled to the array of VCSELs, centerlines of different ones of the micro-lenses offset relative to centerlines of respective ones of the VCSELs by different amounts, the different amounts based on distances of the different ones of the micro-lenses from a center of the array of micro-lenses; and
a projection lens coupled to the array of micro-lenses;

capturing, with a camera, an image of the object illuminated by the pattern of light; and
generating, with at least one processor, depth information based on the image.
