Claim 16:
17. An apparatus comprising:
an optical cell comprising a plurality of different optical elements in optical series sharing an optical axis, the plurality of different optical elements aligned with a corresponding laser of an array of lasers and configured to apply a first modulation to light previously emitted from the corresponding laser that later passes through each of the plurality of different optical elements forming a partial tile of a structured light pattern, a last of the plurality of different optical elements in the optical series having a surface configured to shape the partial tile of the structured light pattern into a unique shape while projecting the partial tile of the structured light pattern for illuminating a portion of a scene, the unique shape depending on a preset random function that defines the surface; and
a processor configured to:
determine a second modulation different from the first modulation by analyzing captured light reflected from the scene, and
configure the optical cell to adjust a modulation of other light when the other light previously emitted from the corresponding laser later passes through each of the plurality of different optical elements to apply the second modulation to generate an adjusted version of the partial tile.
