Claim 15:
16. A method comprising:
generating emission instructions by a processor;
providing the emission instructions to a first non-mechanical steering element configured to function as a diffraction grating;
providing the emission instructions to a second non-mechanical steering element in an optical series with the first non-mechanical steering element and separated from the first non-mechanical steering element, the second non-mechanical steering element configured to function as a deflection element;
generating one or more first order diffracted scanning beams from one or more optical beams emitted from an illumination source by performing, within a first angular spread and based in part on the emission instructions, diffraction of the one or more optical beams using the first non-mechanical steering element; and
generating outgoing light by performing, within a second angular spread that is more than double relative to the first angular spread and based in part on the emission instructions, deflection of the one or more first order diffracted scanning beams using the second non-mechanical steering element to form the outgoing light for projection into a local area.
