1. 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 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.
