1. A method of forming diffractive elements, the method comprising:

  • processing a digital instructional file to generate a configuration for a plurality of diffractive elements configured to produce a complex light wavefront; and

    recording each of the plurality of diffractive elements by exposing a rotating photosensitive medium with a single non-referenced light beam,wherein, during the exposing, the rotating photosensitive substrate rotates at an angular velocity greater than or equal to 10 revolutions per second, andwherein the recording is performed absent other light interference of the light beam.
