1. A system, comprising:
a projector configured to scan a frame of a scene to a subject's eye, wherein the projector comprises a plurality of light emitting elements and a focusing mechanism, wherein the focusing mechanism comprises a plurality of microlenses located in front of the plurality of light emitting elements, and wherein the microlenses respectively correspond to respective ones of the light emitting elements to focus beams of light emitted by the respective ones of the light emitting elements at different focus distances; and
a controller configured to:
determine a depth at each pixel in the scene; and
cause the focusing mechanism to focus each pixel at a focus distance that corresponds to the determined depth at the pixel as the frame is being scanned by the projector,
wherein focusing each pixel at a focus distance that corresponds to the determined depth at the pixel as the frame is being scanned by the projector causes objects in the scene that are intended to appear at different depths to be projected to the subject's eye at correct depths.
