Abstract
A diffractive optical element including microstructures, along a surface of an optical material, having a phase profile to diffract input illumination into structured light of a plurality of different diffraction orders; wherein the phase profile is at least partially phase unwrapped is disclosed. Methods of generating the diffractive optical element is also disclosed.
Claims6
A method for generating a diffractive optical element comprising, calculating a phase profile that produces a structured light pattern;
- unwrapping the calculated phase profile of the structured light pattern to obtain a 2πP unwrapped phase profile;
- generating the 2πP unwrapped phase profile;
- and
- fabricating microstructures along a surface of an optical material based upon the generated 2πP unwrapped phase profile.
