Claim 19:
20. A method of forming a light source, the method comprising:
forming an optical element at a first surface of a substrate, the optical element being configured to transmit an optical signal through the substrate, the substrate having a second surface opposite the first surface; and
forming a diffuser to receive the optical signal at the second surface of the substrate by arranging a plurality of refractive or diffractive lenslets of the diffuser in a pseudorandom distribution to control a particular profile of a resultant beam of the optical signal after the optical signal propagates through the diffuser,
wherein the plurality of refractive or diffractive lenslets comprise first portions and second portions, and
wherein the first portions are positioned on the second surface, the second portions are positioned on the first portions, and the first portions and the second portions have complementary optical effects.
